With Gen 6, the need for a 3D console battle simulator (PBR, Stadium) will be gone. We'll also likely not get 3D console campaigns akin to Colosseum and XD since they could just make them for 3DS and sell more due to the wider install base.

My question is, what will we see for Pokemon games on the Wii U that will be realistic and compelling that could not simply be done on 3DS?
