Nintendo today announced that the new Wii Fit Plus game will launch in North America on Oct. 4, and also revealed new colors for its Nintendo DSi system and for the Wii Remote and Nunchuk controllers and Wii MotionPlus accessory.

Starting Sept. 13, Nintendo DSi will be available in White and Pink, joining the Blue and Black versions already on the market.
