With nearly 1.3 million units in homes, Nintendo's exercise-themed videogame, Wii Fit, has become one of the fastest-selling Wii titles in Japan. Now, Nintendo of America is gearing up to duplicate the success of its parent company. The U.S. subsidiary revealed this morning that Wii Fit will debut in America on May 19 for "under $100." IGN chatted with company president Reggie Fils-Aime about NOA's plans for the project. Reggie discusses how many units of Wii Fit will be available at launch, the massive marketing campaign supporting the project, and how many Wii Balance Board-compatible games are already in development.
