When Activision first announced Transformers Prime for Nintendo platforms, a game based on the kids' TV show of the same name, only the Nintendo 3DS, DS, and Wii were mentioned as planned platforms. If a listing for the game on Activision's official site is accurate, it looks like a version of Transformers Primeis also in the works for Nintendo's upcoming Wii U console, even though Activision hasn't officially announced a port.
Joystiq has reached out to Activision for confirmation of a Wii U version, and will roll out an update to this post if the company responds.
