If its as powerful as the PS3 and/or X360 then it will probably have an ATI R770, with that kind of GPU and a multi-core processor, the system will be a beast. One of the biggest things this controller will do for RPGs is to have a continual menu screen at all times (one less button to push to get to what you want is progress in the development world). Even if it were only the menu screen, I would probably get XIV on the WiiU, I'd finally sell my Xbox360 (pos imo), and be quite happy with my Nintensony duo.

To make a general note about the online experience: Battlefield 3 is coming to the system, so I would assume that the multiplayer and online experience will HAVE to be easier to use (get rid of those damn Friend Codes; or at least have a way to disable them)
