Actually, I think it is much more likely that Apple would decide to come out with it's own gaming system. Or just stick one into an iPod and add 6 buttons to it...
But if Apple did make a gaming system, it would probably be very cool-looking, groundbreaking, and user friendly, because that's what Apple is known for. BTW, I've heard much about how an MPE4 iPod is in the works...
If a tree falls in the woods, do all the others laugh at it?
