One thing people seem to think will go that I think will stay is 3D. The reason being that 1) the tech cost has already fallen a lot judging from the price of the N3DS at launch and 2) they also just invested a lot of R&D cash on the face-tracking 3D so I doubt they'll want to ditch that. Of course, they may wait to hear consumer feedback.
