Ashida regales that in early 2007 the product development team got the first build of Mario Kart Wii and started messing around with developing a steering wheel. Some 30 prototypes laters the team had a design that was about the size of a real go-kart steering wheel and added a B button to the underside of the wheel for a child's fingers to reach. Mario Kart Wii drives into stores April 27... coincidentally, two days before that other driving game.
