To be honest I never expected the wii u to be the same experience as Sony or Microsoft consoles and I shall be buying a PS4 for such genres in addition to purchases of the great wii u nintendo games like Zelda, mario, mario kart etc. However the xenoblades type game for wii u from Monolith is already looking nice and I'm hopeful there will be handful at least of non Nintendo games that reach similar visual standards over the wii u's lifetime. Again I'm not a believer that the wii u is a powerful console but I'm more than happy with the graphics shown. However the crucial detail is how it plays and how much is going on in the world with regard physics, a.i, weather effects etc that will give it that extra atmosphere and playability.
I will be happy to eat my words about wii u power though if watchdog on wii u can deliver something clearly visually better than 360/PS3 with a competitive frame rate.
Watch the third party real on EShop. Watch Dog's looked very good.
