I think the only problem Nintendo might run into if they made something good like the VR'ish idea is that people will call it a gimmick, developers will go "boo hoo, I dont want to spend extra time making a game with VR. I want to make it on a standard boring controller". Then a year later, Sony releases a VR'ish controller/console, everyone goes "OMG, lololz, Its teh gr8tEst th1NG knownz toez manzzz,lolol" and developers start hopping on it until MS releases it too.
