Read!Iwata will show a new game in a few minutes. Other stuff like Smash Bros release on Dec 3, Mario Kart Wii shown, etc. Good times. Strangely, WiiFit seems kind of cool.
10:12: Your in-game Mii actually changes ni visible girth depending on your BMI. Reggie is overweight, apparently. His BMI is 27.51.
10:09: Demonstrating Wii Balance Board peripheral. When playing, can indicate whether you're wearing light or heavy clothes. Balance Board measures how your center of gravity shifts over time, tracks day by day. Tracks Body Mass Index over time. Has graph comparing progression for all players using the console.
10:06: Demonstrating Wii Fit on stage. Features four genres: aerobics, muscle condition, yoga, and balance games. Over 40 activity in game.
9:59: Miyamoto's game: Wii Fit, fitness game with a small floor pad. Seems to detect levels of pressure and activity and mirror your actions in-game to determine your movements and presumably calorie-burning. Also has multiplayer dancing component. Has Brain Age-like progress graphics and stuff. Has balance games where you shift weight on the pad to control Monkey Ball-like game. Seems to have Yoga or something as well.
I need a Wii.
