Last year LaBoeuf told MTV, "I just don't think right now there's anywhere to take [his character] Sam…I love working with Michael. I would do any movie Michael wants to do. I just don't think there's anywhere to take it with Sam." Hmm...a Transformers without Shia LaBoeuf? I don't think his fans will take that very lightly.
This movie would focus on more of an "evolution" story says producer, Lorenzo Di Bonaventura. "We really are going to do a reboot there, and what that's going to be we don't even know yet." Seeing as how the flick would take on a evolution story, of course your favorites such as Optimus and Bumblebee would be included. The obvious character you won't see a return from is Megan Fox, who was fired from the third film.
