I don't have a playstation, so no, I didn't get it. My DS did get the Wii and boxing with him is a really fun workout, so I can see where Eyetoy Kinetic would be a total blast.
I have it, too, and I LOVE it!!! JadedJane, did you see where there's a Kinetic: Combat available in Japan? I hope they release it in the US. It's more martial arts oriented.
Do you play DDR, too? I think SuperNova uses eyetoy.
I think several of the gals at DDRFitClub.com play DDR and Kinetic online against each other.
