I've said it before, I'll say it again, even more important than Mario & Sonic, is that people see this as an equivilant to Wii Sports 2. But put those four factors together (Mario, Sonic, Wii Sports play, Olympics) this is an huge title and it will continue to sell well for the life of the Wii (and do well on DS too).
I expect it to top 10m easily between the two versions lifetime.
