Who thinks the Wii is directly competing with 360/PS3 and why ?

[Desroko]

Yes, they are.

"In fact most of the comparable aspects of the PS3/360 vs the Wii are different appart from the fact that they both play games"

Look to the heart of the matter, not the fringes. They're video game consoles, made by different companies, in the same markets, at the same time. What more do you want?
