The expanded audience has spoken, and they love Wii Fit. Confirmed via NPD numbers, Wii Fit has sold 6 million units in North America, while Halo 3 sold 5.9 million units. That's a huge success for Nintendo, especially when you consider the $90 price tag that Wii Fit has. Even more impressive is the fact that Wii Fit launched in May 21st of last year, while Halo 3 hit on Sept. 25th, 2007.
