CubeChris is right, its not THAT good. ...Well in that picture anyway, although theres one where it does look much better.
If you think about it, Kameo probably has some of the weakest graphics of the launch games, not that its THAT important of course, as its my most wanted Xbox 360 game and I'm confident its gameplay will be immense...I'm just pointing out an obvious fact.
The trees and some of the landscape in that aren't exactly a MASSIVE leap from Twilight Princess in my opinion.
