Like others have said, Halo 3 will be huge, but it's target audience is limited. Many people dislike FPS, and even if they do like them there is so much competition. SMG on the other hand is being described like a game that everyone would want to play (well maybe not die hard PS-360 fans, but still).
I'm really curious about Brawl though... so much raw potential...
Halo: ~10 mil
SMG: ~16 mil
SSBB: ~7-20 mil
