Here's one thing people are kind of forgetting, even if WiiU games are identical on the main screen to their PS360 counterparts, they have to render a whole second screen. Indeed, it's lower resolution, but it's still a performance draw. Just to hit par, it needs to be notably more powerful.
99.9% of games will just mirror the main screen or display a map/menu on the controller which has practically no performance impact. The amount of games that actually render a separate 3D view on the controller will be a tiny exception mostly from Nintendo.
