Can Mario Kart Wii become the nr 1 selling game in its first 12 months?

[Killergran]

Combined Guitar Hero III sales are at 12.41m, with one month to go.

But if we looked at that we'd have to look at GTA:SA's total first year sales. Since the xbox version would then bump up numbers, that would put it over the 12.41m. Maybe around 13m.
