""The Wii affects 360 users, but the effects of that are overrated. I do believe that Wii sales affect the 360 more then they do the PS3. The last one is of course a bit more powerful and known for its multimedia features. I love my Wii, but I really don't have it for that, don't even have it hooked up to the net actually.""
==> I think too
the effect of the Wii is very important !!!
I believe that, without the Wii, MS would be able to sell 2 or 3 fold more Arcade sku (cheap as a Wii, targetting casual as a Wii)
It is why, currently, the Xbox360 is not able to fully use her cheaper entry price compared to the PS3 (280$ vs 400$) : the Wii is stealing casual from MS !
Then the Xbox360 is not able to make the transition the PS2 made fews years ago and it is why the sales are only average.
Time to Work !
