TF2 news on Joblo.com reporting that there is another new cast member: Matthew Marsden. Supposedly, Bay was so impressed by Marsden's performance that he increased his role. They also have photos and a written report from the Bethlehem, PA set.
Special thanks to the commenters who have brought this news to our attention. I wonder if the IDW sequel comic "Reign of Starscream" is set in continuity to the up-and-coming sequel? Time will tell, I suppose.
