Nintendo's Wii Zapper and Wii Wheel are great and all, but what's really going to get those casual gamers flocking is this here Wii Fit game and its accompanying controller. A sort of Wii counterpart to Nintendo's brain-sharpening DS thrust, the Wii Balance Board is a Reebok Step look-alike, with dual sensors that can detect your weight and balance on each side as you exercise to the various on-screen Wii activities in Wii Fit. The board is wireless, and holds the potential of full-body games involving the Wiimote and the Wii Balance Board simultaneously. If you've had enough gaming, you can also have the Balance Board diagnose your body mass index. Or not. No word on when these two will launch, or for how much. Plenty of action shots after the break.
