Oh...so many crazy posts in here...
Well, my guess is:
Wii--->100 million
PS3-->42 million
360-->45 million
Those who call Wii numbers above 150 m are seriously insane, no joke (tough I would be pleased if you were right in the end). Also are the ones who put 360 under 25-30.
I think that at the end of gen Wii will had sell as many as PS3-360 combined
Could be wrong, but I think is kinda probable
