What aspect of Minecraft would you want to be updated next?

Even though the Nether Update was monumental in scale and all around a great addition, I really can't wait for MC to release a cave update.

Features I'd love

• New Ores
  
• New Blocks
  
• More advanced crafting
  
• More Dangerous dungeons
  

What about you guys? :rating:

I would like the End to be updated. Also world generation would be great aswell!

Definitely the End. Nether got updates, so why not the End more? I think the End cities didn't get much love just as the latest Netherupdate got.

Code optimization. The way Minecraft is build is horrible and just isn't right. When you first look at it you may say "This looks pretty clean" but it isn't its a mess and Mojang won't do anything about it.
