Since the release of Wii Fit in Japan in December, over a million unit sales have been recorded. Due to this rapid sales stint in Japan, Wii Fit has proven to be one of the fastest selling games in this new generation of games and consoles.

Wii Fit is a first-of-its-kind type of game, with the main attraction being a balance-board type device that acts as the primary controller. The Wii Fit Balance Board controller is designed to determine your weight and center of gravity, and acts as the liaison between the Wii and a real workout.

There has been no concrete release date for the United States yet for Wii Fit; as soon as we know, you’ll know. You can sign up on Amazon to be notified of Wii Fit’s release and availability.
