ok, my predictions for the games you mentioned
M&S WILL Reach 8.5 million someday, it is still selling and it is not going to stop anytime soon.
SSR will sell a minimum of 2.5 million, unleased will kill it off once it get a price reduction.
Unleashed should sell between 2-3 million it is too early to get precise on that one.
Sonic Riders- I think 1 million is the upper limit here.
So not considering unreleased titles Sonic will sell about 14 million on the Wii... GH is the only franchise that is 3rd party that will even be close.
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
