Sadly, as of now, it seems like Shia is least interested to return to the franchise. Not only that, he had a lot of negative things to say regarding his work with Michael Bay. He even poked fun at Bumblebee, his main protector in the first two Transformers movies.
According to Shia LaBeouf, Bumblebee never really sounds quite real. Just the name alone can’t simply suggest that he is real. He further added that the even the director doesn’t believe it, so it’s a waste of time to be working on an alternative universe. Hence, by logic, Megan Fox shouldn’t be returning to the franchise.
However, if all goes as planned, fans of the popular Transformers franchise can witness the fifth movie in this series, sometime in 2017. According to a TFW2005 blog post, Hasbro recently held an earning conference call for the first quarter. During a Q&A session, Brian Goldner, Hasbro CEO confirmed the existence of the Transformers Cinematic Universe and a possible release for the fifth installment in this franchise.
