20 million seller - highly likely.
Wii Fit - Not a chance (Wii Fit is going to sail past 30 million, and possibly exceed 40 million)
Mario Kart - Possibly.... but I see this coming close to 30 million, which I don't think WSR will unless it replaces the Wii Sports bundle (at which point it would be disqualified from it's own competition)
Wii Play which you seem to have missed - Also no... as it will be another 30 million seller.
