You'll be able to use the Balance Board in the bobsleigh event in Mario & Sonic At The Olympic Winter Games.
Yes, a new Mario & Sonic At The Olympic Winter Games screenshot shows Mario, Sonic, Luigi and Amy Rose racing around a track in in a bobsleigh. To control your team of four, you can sit on your Balance Board and steer by shifting you weight from left to right. You'll also be able to play the game if you don't have a Balance Board.
Other confirmed events so far include alpine skiing, snowboarding and, as you can see in the other new screenshot, speed skating. We can see Mario taking on Sonic on the Vancouver track and it looks as though they're neck and neck as they approach the finish line. Who will win?
Mario & Sonic At The Winter Olympic Games will be released for Wii and DS in late 2009. Are you looking forward to it?
