Nintendo would have to do something along the lines of reworking their OS so that a pro controller can handle everything the gamepad could do if they plan on ditching the gamepad. Otherwise some of their games will not work. Deus Ex comes to mind. That and they would have to find a way to make their online function like XBL. But even this is complicated, otherwise Sony would have done this long ago. No, I think Nintendo has figured out their route this generation, which is a army of fantastic first party games every month all year long. The sales will keep going from there, if they can start working on Bayonetta 3 now.
