I think Sony miscalculated with Move, about how much people would care about real accuracy with motion controls. Its been successful enough, and it's the most legitimate motion controller in terms of giving you pinpoint accuracy, but that's not what the casual audience wants. I was always pretty down on Move versus Kinect, from a sales perspective, because it felt too much like an evolution of the Wii, where Kinect was lowering the barrier of entry even further and completely removing the controller.
Current sales between the PS3 / 360 would look very similar without Kinect. Before it came out, the PS3 was selling more on a monthly basis -- and that's still the case worldwide. I wouldn't call it the go to console in America, but its fortunes certainly shifted when the Slim came out. The 360 owes its current successes to Kinect more than anything. I think Microsoft had the right product at the right time, when the Wii was fading away, and swooped up that big casual market. Sony should probably just keep doing what they're doing now. It's not a bad idea to focus on the more 'hardcore' experiences, just to differentiate themselves from the route Nintendo and Microsoft have taken. Move just isn't going to turn into that breakout device that wins over casuals in a significant way, not in America.
