Having already experienced Aliens: Colonial Marines I'm going to wait with any PS4-XO graphics comparisons, cause while Sony was playing fair, we have no idea if MS did the same and if what we saw is what the games are actually going to look like on XO. But from what I hear PS4 is noticeably stronger (faster RAM, better GPU) while not being more difficult to program for, if not even easier, since it's not using EDRAM to cope with slower RAM. So I guess 1st party games should look noticeably better on PS4, while multiplats should look a bit better and run at a better framerate. That is, unless MS pays major 3rd party devs not to put better graphics on PS4 and to lock the framerate at the same level for both consoles :P But that would be pure evil.
Wii U is a GCN 2 - I called it months before the release!
