Ya the 4x could be to high if it was taken literally... I was using hyperbole to basically say MB would sell more in the long run... Also the 150k a decent bet... I were actually making a bet I would play safer and say 150-200k or 175k... but I could easily see 150k being the final number.
End of 2009 Predictions (Set, January 1st 2009)
Wii- 72 million 3rd Year Peak, better slate of releases
360- 37 million Should trend down slightly after 3rd year peak
PS3- 29 million Sales should pick up next year, 3rd year peak and price cut
