It looks like Bandai Namco will be releasing a product that compete and capitalize the upcoming WiiFit craze. Wii Family Trainer will be a bit more like a traditional game, although you will still have to use the Wiimote along with a floor mat, which looks like a DDR dance mat. Games mentioned are a rowing game as well as a “tramcar adventure”. There also seems to be a two-player mode. This is due out in Japan sometime in 2008.
You can view press release here (PDF) but you'll have to know Japanese.
