I'm surprised that so many people are shocked that characters like Jolt, Barricade, or the Arcee bikes aren't returning. When you think about it Hasbro probably wants as many new characters in each new film as possible. But they have to keep the well known, recognizable guys like Optimus & Bumblebee, etc. It's like the original animated movie. Hasbro wants to sell merchandise. New merchandise. They sold a Jolt toy last year, and it probably didn't sell too well due to the character's limited exposure in the film. They don't want to sell it again. Just remember Hasbro probably has some say on who gets cut too, not just Bay.
