The Hub network has confirmed a few days ago that Transformers: Prime will conclude with a 90-min movie. Very little detail was given in the press release, other than saying this production will serve as an “epilogue.” The war may not necessarily end, but apparently the fate of Cybertron will be revealed.
No date was announced, but presumably this film will air in the Fall of 2013.
Excerpt:
The eagerly anticipated conclusion of the CG animated Daytime Emmy® Award winning series will make its network television premiere as a Hub Original Family Movie. A 90-minute epilogue to the final season wraps up the series that chronicles the epic battle between the Decepticons and the Autobots in their mission to defend Earth and one day restore their home planet of Cybertron. The Hub Original Family Movie is produced by Hasbro Studios.
