Love the MC games and play all 3 versions, (Pocket Edition, PC, and Xbox360) but it would be even greater if they had a nintendo DS version. it wouldn't be reasonable to have a game chip, since you wouldn't be able to update it, but they could have it as a downloadable game from the nintendo shop. that way they could update the game regularly, and you could have almost the same controls as the 360 version. more people would be able to play, you could connect with each other, and it would increase minecraft's fame. just an idea since i love my DS, and minecraft.
Sorry, but it isn't going to happen. Mojang has a contract with Microsoft that won't allow it to be on other consoles. The Pocket Edition was released before the XBLA edition so it is excused from the contract.
I think it would work better on the 3DS. Sorry, Mojang can't put Minecraft on the DS because they signed a contract with Microsoft to make Minecraft exclusive(those greedy swines). I'm betting they could put PE on the 3DS.
