I am SO DISAPPOINTED there's not a PS3 version of DDR available. My fiance and I just purchased the system last week after weighing the pros and cons of Xbox 360 vs. PS3 and now that I know this information I think we're going to take it back and go the Xbox 360 route. I'm glad we only rented games and haven't purchased any yet. I thought DDR was a hugely successful game, so I don't understand why they wouldn't make it fully compatible.
