Bumped.
If it were not for the 360s recent rebirth I think the Wii would be on the cusp of 50%. I think it will make a run at 50% but fall just short of 50% in 2008.
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
