ESPN has been told by a inside source that EA will be reviving the NBA Jam franchise. The source also confirmed that the game is currently a Wii exclusive. The development team will include EA Vancouver along with a handful of developers from the original NBA Jam.
The title is currently planned as a retail title and an announcement is due from EA later this month.
I would say that it is pretty likely, but figured I’d play it safe and mark it as a rumor.
