Wii Fit, the game that's suppose to be fun and healthy. My predictions for this game:
I think Wii Fit will be a lot like a treadmill, or boflex, or weight set. Alot of people will buy it, but most will only use it once or twice and then pack it away or just leave it laying around for show.
I myself have a weight set, a teadmill, and another exercising machine, the only one of which I use is the weight set occasionally. I predict a similar scenario for Wii fit. It will sell well, but alot won't every play, but then again, Nintendo doesn't care as long as it makes money.
