under tracked by around 1 million. The general rule of thumb has been take the shipped number - 1 mil to get the ballpark. Of course that does not apply when something is supply constrained which the PS4 is currently not.
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
