Each year Madden's sales on the Wii have grown. I would even go as far to call them respectable, that is something the last few Nintendo System's could not say.
Note- the reason Madden 2007 tracked so weird is because it did not have the usual august launch, it came out with the Wii in November therefore did not have the traditional Madden double bump. (look at most maddens, they have it)
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
