Everything is always money, money, and money. It's important for business, taxes, and the way of modern life. But, there's so much things that only a person could want that's labeled with a price. What I mean is, at least on annual occasion, set one or two skin packs for free. For example, if it's MineCraft's birthday tomorrow, set it for a week to get the free skin pack, a lame one for all I care. Or, if it's for a special day that reached the most sold items, something could be for free at least a week or a couple days. It might take updating or so, you can always do it before a new MineCraft: Xbox 360 Edition update for a new version along with bug fixes (if there's any). At least put something priced for free annually but not daily or monthly. Lots of people buy this game, buy the features in the game, supported the game, so why not reward these people with quick small updates or free items or whatever you'd like.
Terrains and Animals/Creatures
Definitely, I'd love to see the mushroom biome especially along with new animals added into the game eventually. For example, mooshrooms. To me, they look very cute and I'd love to see them some day. Add spawn mob eggs! Especially in creative, if you would like to practice or test out "experiments" with mobs. Do at least, have just a good enough amount of caves and especially a "realistic" biome separations. What the heck do you mean? You may ask. I will answer: no deserts near snow biomes. Deserts are a hot environment and snowy terrains or biomes are not, it's chilly, cold, and freezing. It doesn't just mix. Let's try to fix that... You could also add animals like ducks or insects. Insects could be fed to chicken which could be another way to mate. Insects could be cooked in furnaces and could fill half a meat. Ducks could be treated like chicken when you eat them. Ducks could hang around eat fish and when you kill a duck, you'd get feathers, the meat, parts of a fish, you know. And those parts of the fish, they could be used as bait for the fishing pole to attract squid. Make squid edible, it could heal two or three hunger and one heart. It could be cooked in furnaces.
Add more sweets like how you added cookies and cakes. Add layer cakes, pile the cakes on the tool box and it could heal two times more than eating one cake. Pancakes or waffles, maybe? You could use the same recipe as the cake but to modify it in a twist to make it a pancake or a waffle. Something sweet to eat. I also would love to see soups. There's a mushroom soup already, so why not add in just plain soup water and it heals half a heart. Why not add in boiled egg soup, or something like that, thing you could find in the nether, ender, or even so the "spawned-world".
Try to suggest some things yourself, list it out the way you like and be descriptive to the ones who read it.
