Wii and Ps3 going at it for a decade. 360 too? How will the sales go?

Wii - 7 Years (About a Year after Wii 2, the Wii dies)

360 - 5-6 Years (360 dies as soon as 720 releases)

PS3 - 10 Years (New Console after 6)

I should clarify.  Neither Microsoft or Sony will deliberately kill their consoles once they bring a new one out, its just that neither will have tails as good as the PS2 because they failed to reach an equivelant critical mass.
