2.0.0 will probably never be out because

1. It is updated enough to be super awesome in the first place
2. The team are too busy making other games
3. Users don't want to have to pay $30 more to play another update.

-Who

A bigger selection of decorative creative blocks, because I only play creative

Replace all blocks with spheres

Flying hippopotami, cuz yolo.

NUCLEAR CREEPAHS

Nuff said

An in game starting tutorial.... Do it now jeb!!!!! not everyone knows how to play the game when they get it!

Quests.

Towns / Guilds (Tales of Kingdom like except you can't build your own kingdom)

Make Gold sellable or tradeable with the Towns to purchase items.

Nanosuits? You fuckin kidding me? I want to see the modding API along with better heuristics and code optimization. Despite being fun and popular, it's horribly coded, and optifine only adds minor improvements. Hate to say it, but if a company like valve had control of Minecraft, it would run so much smoother (at the sake of the fun and creativity that Mojang offers)

tbh I doubt that we'll ever see Minecraft 2, but here's what I have to add.

SkyTechKidWhat I want that it is possible to have free servers for adventure maps to play with friends. Kind of like a dedicated server for everyone.

That would be COMPLETELY impractical for Mojang to do, but there's this

You need to get a better computer for no lag... mojang can't type some code
and then they'll be no lag

Sorry to say this but that sounds pretty stupid. Minecraft is written in Java, which is slower than some other programming languages because the code is read line by line by Java instead of already being compiled, so Minecraft would actually be less laggy if it was written in a compiled language such as C/C++/C#. (This will never happen, however )

i0wnageeI would want JETPACKS! but only in CREATIVE.

by the way check my server? vvv

Creative fly already exists. I'm assuming you mean a jetpack item that can't be crafted but jetpacks don't really fit into vanilla Minecraft. I love your shameless self-promotion though

BleydAsymmetrical skins, balanced PvP, voice acted NPCs, an overworld boss, and larger vehicles in the way of either placeable items or movable block groups.

Soo... Make Minecraft more of an RPG than it is already?

In my opinion, theoretically IF Minecraft 2 were to be made it should be a complete rewrite with improved mob AI and physics, and should be a circular world like that of Castle Miner... Also, the gameplay should be more based around multiplayer, because as it is one person can get everything they need and essentially live underground forever. I think that farming should be refined to be less productive (for example having seeds not always drop from crops), and animals should die of age after a certain time. I'd like to see some way to have the game evolve over time, too. Getting iron tools is far too easy imo. Just my two cents

I would like:
Shields (Made out of Iron, Golden or Diamond only)
Guns
I know this is funny but how about Golden/Diamond Computers?
Player Heads
Pots/Vases
Giant Zombies in Hardcore
and I would like it if you could put Written Books in Bookshelves and be able to take them out of the Bookshelf they are in.

Thanks!

it would be cool if they had a program like Hamachi in the background of mc that you can't see and it lets you run global lan worlds but like all the clients are connected so no network connecting needed you would just like maybe type in {playername}.minecraft.net and then bam your on that players world but maybe like a whitelist feature

Give us limbs..?

Idk

Obsidian Tools and Armor
Bedrock Tools and Armor
The Aether
Another new dimension
Sword Pedestal
Armor Pedestals
Golden Potatoes
More crops
more food
Some more mobs like snakes or bunnies.

wow, all good ideas!

thirst bar maybe???

Maybe.. umm... A new kinda fence... iron fence... that's all... probably all that's gonna come...

And nano suits (from tekkit?) wouldn't really be minecraft-y XD
