I think it doesn't make a difference for Nintendo were the users are storing their Wii, at least they are buying it, most people tend to not store a PS3 at all, so you can say PS3 rules the storage rooms of the retailers.
I must admit, that I am tired of all this ridiculous statements from Sony. They behave like people who loose a game and try to blame the other players for not letting them win.
The videogames industry still has serious problems. In this situation Nintendo was the only one who seemed to understand what the problems were. Sony's strategy was bigger, much bigger, much much much bigger. Now there strategy lies in ruins and they seem total incapable of some kind of self-criticism.
