While few details are currently available, Apple announced during a recent event that Minecraft will - along with a host of other applications - make its debut on Apple TV, according to an announcement by Apple's Tim Cook during their live event. A handful of details are available: it will not be Pocket Edition, but rather a version called Minecraft: Apple TV Edition.
It is not known if this version will differ significantly from other platforms, but there is little reason at this time to believe it will.
Minecraft has, over the course of years, slowly become available on nearly every popular platform in use today, and quite a few obscure ones besides.
This brings up an interesting question: do you play Minecraft on multiple platforms, or just one? Do you have a preferred platform? If so, which one and why?
