Several things here:
1. There is a revolt against motion control by hard core gamers on here and around the forum. There is whining about the need to move your body, and not use a regular pad controller. How does Move manage to breakthrough this and get core gamers to care about motion control?
2. Exactly how much fullbody measuring and control is done with the PSEye? If it was able to fully do this, then why was the wands added? The Wands are used to give you a lighted light bulb, so it would track depth and where the controllers are. And throw in the Wii here also, and ask what system does what Kinect does, in regards to tracking body motion? How much did Harmonix lie when it said that Kinect was the first system that they ran into that did what they needed for a dance game?
3. In regards to appeal to casual, why are casual gamers going to get drawn to Move, when Move does what the Wii does, and still is a controller in the hands? Is greater precision, and better graphics to get the casual gamer to spend more money again, to be able to get a new system and more controls?
As I see it, the success of Kinect depends upon whether people want a full body movement experience for games. If they just want to move their hands and arms, then the question becomes exactly whether or not Move is sufficiently superior to what the Wii does that people will buy a PS3 over the Wii to do this.
