The market disagrees:
1- The PS3 and 360 combined are selling at lower levels than the consoles of the previous generation (on a time aligned basis) even if you ignore the Gamecube.
2- The tie-ratio of the Wii and PS3 are very similar, in Europe the Wii actually beats the PS3 with this metric.
Sure, the Wii is also appealing to a new audience, but does that put it in a separate category?
PS: I'd like to know how you figured how much time Wii owners spend on their consoles.
