[Edit] Nocte has found that it is only Semi-Cubic. [/Edit]
Jeb has released a page of info detailing his new "Anvil" World Save Format for default Minecraft. This format will start being in Minecraft as of this Wednesday's 2012/2/15 12w07a weekly snapshot and thence forth in Minecraft v1.2. Minecraft will auto update your worlds but Jeb has also released the Converter and it's source-code on the info page already linked to.
This new World Save Format and relevant game code add many mod-friendly features and capabilities to Vanilla Minecraft. The Most important of which is that Minecraft is finally leaving behind the old rickety Linear Chunks method and instead adopting a limited height (256) version of the 3D Chunks methodology! This will allow 256 High world games to possibly be faster even than the original 128 Linear Chunk worlds were. :smile.gif: It's been tested in SMP and Jeb reports it to be solid.
Jeb is also adding another of Robinton's ideas into Anvil, native support for 4096 BlockID's! He also gave a shout out to Robinton and his Mod thread at the end of his post, the clear inspiration and demonstration of these features being implemented in Minecraft. :smile.gif:
Robinton's Cubic Chunks Mod is still needed, offering far greater Height + Depth than Anvil, as well as more Terrain options. So please encourage Robinton to keep up the good fight! :smile.gif:

[ /Update ]
Jeb has announced possible plan to
Increase Default Minecraft World Height! (And SOON)
From the below stream of tweets and responses I have summarized the following:
Jeb is seriously considering raising the Default Minecraft World Height, and soon.
It will likely be raised from the current 128 blocks high to 256 blocks high.
The Minecraft World Terrain Generator will not be changed, so Terrain will remain at current height.
The extra space/height added will be open air, likely an extra 128 blocks of air going up.
You will NOT need to start a new world.
Jeb will include a Converter so you can convert current 128 World Saves to the New Height.
Your converted World will not change except that it will have more space above.
[EDIT_2012-02-09] * More Info from Jeb. Tweets added below in the Tweet section. Pic added below:
Jeb has Higher World tests running on the volunteer treesquid server that he is profiling. Says it's going well.
Jeb is referring to the "New World Format". Is this just the basic extension to 256 or a whole new optimized format?
[EDIT_2012-02-12] * More Info from Jeb. Tweets added below in Tweet section.
Jeb has essentially confirmed that the "New World Format" he keeps referring to is a more substantial alteration to the current World Save Format than just extending the Height the way fishtaco's Height Mod does.
Jeb says that the "New World Format" is a part of his upgrading Minecraft to support Modding.
Jeb says that he will be releasing Documentation for the "New World Format" so that modders won't have to dissect it to understand it.
Here are some of my current thoughts and predictions regarding this:
Since it will be Default it should also work for vanilla Servers
This height increase is certain to be using the current minecraft Linear Chunks, unless jeb has a Huge surprise for us.
Slower computers will feel a noticeable drop in FPS, unless jeb has found new improvements.
After many speed complaints Jeb might make 128/256 Option for Worlds, or just drop it.
Spoutcraft is already capable of Linear Chunk 256 height, and more. So fast update. [Video]
bukkit is connected with Jeb so I'm sure it will be ready quickly.
I have tweeted Jeb with some more questions about this.
Having a 256 Height Option in Default Minecraft would be Great!! :smile.gif:
More room for Skylands?

Even air blocks are blocks. Having played for the past two months in a 256 world, the lag over 128 is barely noticeable, though. And I don't have a great PC.
50ish FPS in a 128 world, 40-45ish in a 256 world.
But yes, cubic chunks would be great. It would provide performance improvements even in 128 worlds.
Doubt it. More chucks to update and he can't increase the clock in the code otherwise the lag would get unbearable.
As of now, it is 20 ticks a second... So basically your computer will die if it has more chunks to update than already - I mean, even on a fast computer, the chunks can take time to load/update. It's not the computer, it's the code.
In the OP I make note of Jeb referring to the "New World Format". It made me wonder if it's just the usual Minecraft world save extended to 256 height like fishtaco's or if he's made more extensive alterations to the World Save Format.
Well; a new tweet from Jeb confirms that there will be more newness than expected coming with his "New World Format". Also; Jeb is creating more Texture space for Minecraft. See Below:
I agree but it MUST have a configuration to how tall it can be, so if you have a better computer sutible for that increase, you can top up the hight as you please, but if you have a slow netbook, you can keep it 128.
A extra document in the world file that controls height will be good, you just replace 128 with 1024 to make yo limit sky-high!
And a height button in create new world page and height=128 in server.properties for noobs who don't know how to do the advanced stuff mentioned above.
