The 2DS is literally a flat 3DS without the "3D" simulation/effect. It's possible, and even one of the Minecraft developers say it's possible. The thing is, they said it might be a little difficult for the 3DS/2DS system, so we probably might not see that anytime soon.
well there's minecraft pocket edition (android and iOS), minecraft ps3 edition, and soon to be released psvita edition (playstations/sony are rivals to Microsoft and stuff). so, Nintendo versions are very much possible.
also the "exclusivity" for minecraft and Microsoft PC edition also includes macs which are made by Apple, so...
