Wii U will definitely surpass PS3 and 360 down the road with more shaders and once they can utilize higher polygon counts. It will probably take 2 years for the average game to start showing off, but we know by then the new consoles will already be outperforming. As long as Wii U can keep some visual fidelity, maintain gameplay delivery 1:1, and throw in some second screen features, it will be fine.
Before the PS3 everyone was nice to me :(
