Wii Fit demonstrates Nintendo’s commitment to gamers of all kinds. It combines fun and fitness for every member of the family to keep active and play together. Wii Fit launches May 19 in the United States and comes with the weight-and-motion-sensing Wii Balance Board that Nintendo representatives demonstrated could hold great promise for future game development as well. Third-party publishers are already working on new games and applications that will make use of the Wii Balance Board. Additionally, Wii Fit includes access to the Wii Fit Channel, an interactive channel that lets users check in each day to track their fitness progress through weight and BMI. In Japan, Wii Fit has sold more than 1.4 million units since its Dec. 1 launch.
