There was a Reason, I put Weird and stupid in it didn't I?
But it's true Kinect has been dumbed down, and consumers most definitely aren't going to buy a shitty eye toy. It ain't going to sell, simple. That's why there promoting the shit out that piece of garbage, it may matter to the causuals, but to the gamers out there, HELL NO.
Kinect will sell to people who own a 360 simply because that's all they have. They won't be willing to buy a PS3 just for a peripheral they can get for a 360.
