G4tv.com reports that the ESRB website had listings for NBA Jam on PS3 & XBox 360 up. The game has been marketed as a Wii Exclusive since its announcement.
It is now being rumored that the Wii version will be a timed exclusive, with the PS3 & XBox versions coming out in the spring. Perhaps Move & Kinect will be incorporated as well?
ESRB has since pulled down the listings.
