All eyes -and thumbs - this month will be on Grand Theft Auto IV, but some think a sleeper hit waits in the wings: Wii Fit. Another out-of-the-box game cooked up by Nintendo, Wii Fit is a balance board that you use to for a variety of standing/jumping/balancing games. I played it last year at E3, and it was one of the few game-changing games in town - something truly different that gets a whole new range of gamer muscles working.
Now after becoming a runaway hit in Japan, Wii Fit is anticipated as having a tidal impact on the U.S. when it arrives on May 19 (the game hits Europe this month and Australia next). One analyst predicts sales of three to four million units by year end.
