The numbers don't makes sense really. All(most) of the major stores near me had great stock of Wii. Is it possible the the stores in ioi's sample just got smaller shipments therefore screwing with his population data?
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
