Everybody talks about that there are no games for the PS3, that surprises me, at least you have 4 or 5 excellent games, on the Wii you don't have even one, I know what you are thinking, what about Zelda, well I think Zelda was not that good and I would play Ocarina over and over again and not this one.
The real next gen war is between PS3 and 360, the Wii is not a next gen console, it's something different but not a next gen console.
Personally I own all 3 systems and I prefer the 360, the games are amazing.
