If they make the right game for it, or convince big third parties to do the same, or both... it'll be alright. I have a feeling we'll never get something as immediate as the motion control phenomenon (because it was) again but, looking at it another way, there's no sense in bringing out a 'revolutionary' controller like the GamePad if you haven't already thought up lots of different ways to use it. Hopefully Nintendo won't make that mistake again. *crosses fingers but does not hold breath*
