What is the lowest realistic expectation for lifetime sales of Wii,PS3,360?

[He300]

I belive we all agree to this = WII > X360 > PS3
if we all can agree to that, then why should we argue about the details?, 10 millions this and there, who cares?
the big thing is that nintendo is back and kicking ass and taking names:P and that sony is......out?
