PS EYE can do what NATAL can:

PS Eye/Move is far more superior. http://www.thesixthaxis.com/2010/05/17/natal-guesses-players-movement/ Also PS Eye doesn't require Move to work, Move requires PS Eye to work. PS Eye/Move has way more possibilities for games. Also Sony, along with Nintendo, were also offered the technology but didn't take it because of their production cost.

The PS eye does NOT do 3D gaming well at all, watch some of the videos...they look more laggy than Natals tech demo...not good. BTW, look at the addy of the link you posted, Biased and ignorant fanboys, the whole lot of them. Natal uses software to track the bodies motion, it doesn't just "guess" where the body is. 

 

 

Lag is due to processing time. Natal uses IR light while the PS eye uses visual light to track. You know about those 28 (?) points on body natal suppose to track. Well those points are not detected by the camera itself. The  software (Cpu) has to add those points on each IR frame. To save time (reduce lag) Natal will probably have to guess some if not  many of those points. This is the advantage of have something to track that is visible on camera. It requires less processing time.
