Playstation Move vs. Xbox 360 Project Natal

Playstation finally came out with a name for their motion controller. Playstation Move is told to be more fast, precise and accurate compared to Nintendo's Wii remote. Check out the trailer to see the Playstation Move in action. 

Last June Microsoft announced it's "controller-free gaming and entertainment experience" 
called Project Natal. It looks really impressive and more innovative compared to the 
Playstation Move. Which of these two will prevail? We will just have to wait and see. 
I was thinking of getting both of them.
