If Apple makes their own version with game controller support ... it is so on.
I think honestly this is Nintendo's future too, they won't make another dedicated, unique console anymore, their next handheld will use a modified mobile (smartphone/tablet) chipset, and that same chip will be put into a micro-console box about the size of a deck of cards for separate purchase if you want to play on the TV.
Maybe the home version will be overclocked with more RAM so the TV box can run in a higher resolution, but otherwise it'll play the same games as the handheld with similar visual quality (I'm guessing right around what the Wii U does currently). And it will be extremely cheap.
If Apple decides to make their own version though, that will be the one most people lean towards.
