Hmm.. I'd have to say a canyon.. and not just ravines chucked into a mountains biome.. i mean like the surface is hardened clay and there are tall rock faces and the possibility of a river below.. yeah
Probably some kind of rare (like Spider Jockey rare) Floating Islands Aether type biome above the clouds, some tropical islands in Oceans or a new kind of Underground Biome, maybe an Ender infected area with Endstone and more frequent endermen near strongholds?
EDIT: And a really vast, wide and deep ravine/canyon, that would be epic.
First, and more importantly they should add cubic chunks. Then they can get onto the good stuff.
Mountains: Real ones, not the extreme hills variety but REAL mountains with waterfalls, caves, snow capped peaks, ridges. This needs cubic chunks to be implemented, as I would want to see mountains that are hundreds if not thousands of blocks high.
Sky Islands: Large islands in the sky with waterfalls, trees, villages, and animals.
Deep Sea: Less of a biome and more of an improvement to oceans. In deep sea biomes the ocean extends deep into the earth, hundreds of blocks, in deep trenches. This should have new ocean mobs as well.
Coral Reef: a reef underwater filled with coral and new animals.
Archipelagos: Islands set in the ocean (think like the Hawaiian Islands) near to eachother and with specific mobs unique to the archipelago.

This guy is pretty cool: Hey! I like, run this... or something:
Skybound Biome: A biome found in the sky that consists of floating islands that size ranges from medium to small chunks and sometimes a large one. Ores can be found and villages, dungeons and mobs can spawn on the chunks. A biome-specific tree can be found here, as well as a biome-specific ore called Skyla Ore. It can be used as crafting and it's armour and tool use is in between Iron and Diamond. A new mob is found here. Herons fly and hunt for fish in water.Skybound Biome: A biome found in the sky that consists of floating islands that size ranges from medium to small chunks and sometimes a large one.

Also add new features like waterfalls, fjords, higher mountains to 256, more tree variation, make extreme hills grass color less dull. Add a hills, and an extreme hills variant of every biome. So you could have a desert extreme hills. Less water pockets in deserts. More flowers, more tallgrass types.
Trees are replaced with hat racks covered in various fine hats. 1% of the hats are Unusual hats and come with an enchantment. The rest are simply headgear with the same protection level as leather caps. You can wear multiple hats, but they don't give any further armor bonuses.
All mobs that spawn in the hat biome are equipped with hats. Beware of Skeletons with Unusual hats.
Players who enter a hat biome without donning some sort of headgear are afflicted with the "Poor and Irish" condition that is a combination of Slow and Hunger. Staying in the hat biome for too long will cause the effect to worsen, rapidly reducing health. Putting on headgear instantly cures the affliction.
Hats constantly rain from the sky. When they hit the ground, they turn into a Hat block that is much like snow. They can pile up over time. Hat blocks can be harvested by hand.

Revamp the current biomes first, they still need improvements, the swamp, jungle, desert, ocean, etc.
There's a rumour says that dinnerbone is going to add seasons on future patches, which I think is awesome, so they should consider the biomes compatibility for it. Because I can't still imagine a rainforest jungle has snows on it.
If could the new biome, would be a Deciduous Forest! with fallen yellow leafs, and darker dirt.
Honestly, I agree with a number of other people here;
Improve the mushroom biome's spawn rate, add volcanoes, and also the Mediterranean biome idea.
Particularly, I like Toucan687's idea of the Japanese Jungle. A more worldly feel would do well for Minecraft. You could even go so far as to include Chinese, Japanese, and other Eastern-esque Temples complete with Torii Gates.
Quite honestly, I would like to see the sky islands idea somebody mentioned earlier, as well. And please put in more temples.
Sky Temples (obviously in the sky), Water Temples (underwater), Void Temple (in the End) And if and when volcanoes are added, Fire Temples!
Alternatively, you could just put the fire temples in the Nether.
More diversity, please!
....
At the very least, more temples.
What I would like to see isn't so much new biomes as improvement in current ones. Mud Blocks for swamps, more realistic mountain rages with snow, I mean they have all that extra world height now. Reefs/shipwrecks in ocean biomes, maybe even limestone blocks in beach biomes. That sort of thing.
A chain of Volcanic islands, or an extreme mountains biome, with glaciers and mountains made out of stone. The mountains would be jagged and glacially dissected. The volcanic islands would have a trench on one side.
My first suggestion would benefit greatly from an increase in ocean depths and includes semi-exclusive structure generation: An Atoll biome. A ring of tropical islands surrounding a shallow lagoon. With a possibility of either a mushroom island in the center, or a volcano in the center (Like Redpower2's ocean volcanoes, resembling a shield volcano). Along the outside of the island ring, shipwrecks would have a higher chance of generating, as compared to generating on the ocean floor. Unless on large biomes, this biome would be a disappointment to find. As would the wrecks, on normal biome size, they would be small, about gunboat size. On large biomes, they could pass for large frigates. On Mystcraft's Huge Biomes, the could easily be Ships-Of-The-Line*.
*Cannons & crews not included. Nor will they sail...
Secondly, a mountain chain biome. A highly linear biome when seen on the map, it goes in a line that could be tens of miles long, but not even a tenth of that across. Even in normal biomes, they could easily be the largest and highest land-biome available, reaching possibly Y-230 and beyond. In this biome, 3 unique sub-biomes could exist:
-A canyon, which would basically be a ravine on steroids. Being up to a mile long, 60+ blocks deep, and more than 100 blocks across, they would be a sight to behold. There would be 3 variants: Glacial, which has it about half-full of ice; river, which has a large river at the bottom; and dry, which has a dry riverbed at the bottom. Dry riverbeds have more clay and some ore-bearing gravel. Ore-bearing gravel will drop a random item when mined: ranging from a flawless emerald (Villagers give 3x the trade item in question for the same number of flawless emeralds.) to a lump of hematite (Smelted to yield iron.), Fortune-affected, so an enterprising miner with a good pick could become a very rich miner indeed.
-Also the waterfall sub-biome would be present in the mountains, ranging from a small trickle to effectively Niagara falls. To make this make sense, rivers in mountain chains would be much wider & deeper on average.
-Lastly would be the Volcano, unlike those in an Atoll, they would be steep-sided, & made of obsidian, cobblestone, & have a denser ore concentration than normal, with any ore being found at any height.
My last suggestion is a town sub-biome: This is basically a larger village, but with a more sensible arrangement with farms near the outside & residences nearer the middle, and a larger number of structure templates to draw from, ranging from libraries, town hall, and animal farms, to small warehouses, guard towers (With some new form of golem with a damaging range attack at the top.), and harbors if on the waterside. These have the highest probability of generating on Atolls, or on Plains-style biomes. However, anywhere a vanilla village is generated, there is a chance a town will generate instead.
I would really like to see a desert biome but now like the Saharra style desert we have now but an American desert with canyons, buttes, plateus, and a different color sand. The sand in that biome could be colored much like grass is now with different biomes.
For me it would be a tropical island chain, not as many trees as in the jungle or the forest but more than plains or mountains, also with it I would like nicer looking clearer water.
Archipelago with some nice large islands and exotic plants/trees.
Extreme hills should be renamed Chaparral, and then a mountain biome should be introduced with new ores like copper, tin, and other nice gems like rubies and sapphires.
River biomes should flow somehow, I feel like all the stagnant water would become swamp.
Not going to include mobs/mechanical stuff cuz that's too deep into what the thread's asking.
EDIT: And a really vast, wide and deep ravine/canyon, that would be epic.

Great idea, right?
where the trees are so dense and tall that its very dark and ominous.. good for spawning monsters.. there may be structures here too..
You've got a great fantasy

If you're not sure what I'm talking about. Here's a photo of what kind of desert I mean.

Just loads of small islands floating in the sky.
They could all have some ores inside aswell.
Either that or floating islands. That would be amazing!
