No Im not interested in Natal, but I can't wait for ps move, also I already own a wii, and ps move has been confirmed to be better already than the wiimote, which is the only reason why i am going to be getting it
Edit: also you should be asking the wii user base this question as well it will be interesting to see the results.
it's the future of handheld
