The competition is in the games. This hardware shit you're harping on is crap. None, and I do mean _NONE_ of the hardware is innovative. It's all been done before one way or another. Each of the 3 are just picking up ideas that have been talked about before and making them slightly better. None of that matters.
Do they have good games? Do they have enough first party and third party support? Can they make profit enough?
The End.
