Nintendo busted out three new Wii accessories during yesterday’s E3 press event. First up is the Wii Zapper ($TBA; Fall 2007), an assault weapon-style unit that holds both the Wii remote and Nunchuck controller. It’ll come packaged with “Nintendo-developed software,” but will also work for games like Resident Evil: Umbrella Chronicles. Next, Nintendo showed off Wii Fit and the Wii Balance Board ($TBA; 2008). Together, they take fat-burning workouts to a whole new level Wii Sports could only hope for. The pressure-sensitive device works with the Wii Fit game to let you do aerobic, toning and balance activities. Finally, the big N debuted the Wii Wheel, a mini steering wheel housing for the Wii remote that will ship with the forthcoming online-enabled Mario Kart Wii ($TBA; 2008).
