Shia Says He's "Done" With The Transformers Franchise

During a recent interview, Shia revealed that he was done with the franchise "for sure" and added that he didn't think he was the only one. He explained:

"I'm not coming back to do another one. I don't think Mike [Bay] will either…It is still a hot property I think, especially coming out of the third one," the actor continued. "So I imagine they'll reboot it at some point with someone else."

So who do you think would make a great replacement ?
