Sony Reckon Playstation Move's Accuracy Make It A Vastly Improved Experience.

The Sony man states: “[Move] is better than Natal for a few reasons, but the biggest reason is what we call draw distance. What Natal has is very XY, you’re playing in this realm [waves hands]. So for games that are shooters, or golf, or sports, if you draw back away from their camera you loose precision.

“The sphere that’s read by the camera, is very precise so every move you make, many feet beyond the camera, allows it to track. The fact that you can use the camera and the motion controller provides not only tactile experience, but the camera can pick up both audibly and visually.

“So, more to come on that too."

Also Move has buttons and rumble - essential in giving you some semblance of feedback.
