Will WiiFit, MKWii and SSBB outsell SMG in a month's time.

[TWRoO]

Mario Kart Wii could manage it in 4 weeks... SSBB will not manage it within a month, but will shortly after (probably 6 weeks)

Wii Fit depends on supply, I doubt it will make it within 4 weeks though... it will probably pass it in the same week as Brawl.
