How much will Fit outsell Brawl by in NA this year.

[MontanaHatchet]

Explain to me why Wii Fit would sell well in NA?

Japan and Europe maybe, but trends have constantly shown that casual oriented games don't sell nearly as well in NA.

Brawl will easily outsell Wii Fit lifetime in NA.

First year?

Brawl vs. Wii Fit anywhere from 8:1 to 10:1.
