A great step in the right direction (Score 1)

I think this is a great move! While there are some doubts about how much gamers will use this I think it's important to remember that little changes can make a big difference. While it's true an obese person isn't going to become a conditioned athlete by using the treadmill for 20min-30min a day, that's enough to make some changes in the lifestyle of dedicated couch potato gamers. It's more than the nothing many of them are probably doing now. Maybe once they realize they can jog for 20 min while playing the game they'll give it a shot outside. Further, people do get fitter; it's very possible over time that 20min could turn into an hour.
