If rumors are true and the GPU in WiiU is based on the chip of ATI HD4xxx series, then it is sure that it is more powerful than PS3/360, hands down. And besides that nature demo, with was ok, and the Zelda tech demo (which for me looks better than that God of War 3 video if only for the lights and the fact that the Scorpio in Zelda has hair), we haven't seen what it is capable of. Even the 3rd party games footage was from their PS3 or 360 versions.
And what's the point of talking about a demo we can't see? Yes, it may look great and all, but it's useless if you can't show it to us.
That said, PS4 and the next Xbox will be more powerful. By the lack of new games from Microsoft it is pretty clear that they are working on a new console which probably be based on todays hardware. Assuming that, and given the problems they had when they went from Nvidia to Ati, they will probably stay with them again, using todays hardware: the HD6xxx series. That's 2 GPU generations between WiiU and Xbox720. Now check what ever site you want and you will see that even at 1080p the HD6xxx series is far more capable than the HD4xxx, both in terms of frames or goodies like AA. And Sony will go the same route, just to be competitive with Microsoft.
Will these console be expensive? Yes, but we are talking about Microsoft and Sony, losing money during the first years is not a problem for them.
The question is, will this difference in power hurt WiiU or will it be powerful enough for developers to still develop for it?
