And Wii's sales don't convince you either?
I don't exactly see what this has to do with my comment.
Either way, I think there is a sizable difference between a product that retails for $200 and gives you a complete experience, and a product that could run you anywhere from $150 to $450 (depending on your status as a consumer, own, don't own, etc).
Of everything they've shown, the only thing I can see being a commercial success at this point is Dance Central. I don't think Kinectamals or Kinect Adventures have any staying power, as the 360's age demographic is a bit different from the Wii's. I understand they are trying to expand the market, but I just don't see that happening. We'll see though.
