We knew it was coming, but now it’s official. Wii Fit is on the way. The game will come with a wireless balance board, capable of measuring your weight amongst other things. The title will feature over 40 activities. Much has been made of Wii Sports‘ ability to get us lazy gamer types of the couch, this looks like it will take things a step further. The game is expected in Japan at the end of the year, 2008 elsewhere.
