Wii should pass PS2 this cmas in games in the top 100 sold. Very nice. Now I know that the PS2 had a crapload of games sell 500k to 1.2 million over, and the Wii has only a couple.... but still the Wii is top heavy.
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
