I would really love to see a legitimate "copy" of Minecraft (one that's made by a serious company, not 10 year olds in Unity) that would support modding through lua or other very common "plug & play" scripting language and would have fixed everything that Minecraft is doing wrong at the moment including engine, hitboxes, collision, reasonless lag unless you assign 1 terabyte of RAM to the game and so on and so forth.

Infinite worlds!
Caves!
Loads of new blocks and items including Monster Eggs and huge mushroom blocks.
Wolves! Tame a loyal companion.
Loads of new flowers! So pretty.
New mobs, including the spooky endermen and less spooky Mooshrooms.
New biomes from the PC version, including mesas, jungles, swamps and extreme hills.
Abandoned mineshafts, villages, and many other cool places to explore.
A brand-new “interaction” button. Never accidentally punch a sheep again!
New feature generation, including lakes, vines and monster rooms.
Many bugs fixed, and possibly a few added.
This is a pretty big deal, this essentially makes Pocket Edition a lot more closer to PC thanks to Infinite worlds and everything that was included from PC generation and all. Infinite Worlds and Caves are the biggest updates in my opinion, same as for the mineshafts and "places to explore".
