Expected and I can't see way better games in future for Wii U or even 1080p.
Based on what? Is it your official break down of the wii u or it is it just all the wii u not stronger bull?
I believe a console does improve over time, as developers learn to explore its potential. However, the improvement is only marginal, meaning the first wave of games struggling to top past generation consoles already says a lot about a console's power.
A PS2 game might have a team of absolute wizards behind it but it still won't look like a PS3 game. That's the problem with Wii U, even if its potential is fully tapped, it's very likely it still won't be enough.
