Attention to the dancing enthusiasts. Unfortunately I am announcing that the DDR SuperNOVA 2 North American Field Test has been canceled. I apologize for this inconvenience, but look forward to bringing you more information in the future.
No further reasoning was given at this time, but we’re hoping that they are taking their time with any errors that have been found. We’ll update you on the matter once we find out more.
