Producer Lorenzo DiBonaventura says that the fourth film is definitely planned for 2014, and that Michael Bay will direct, despite any back and forth statements to the contrary.
MTV spoke to the producer, who said,
Michael’s going to direct it, and it’ll be in the summer of 2014. We’ll be releasing it [then]… I think the challenge there is we really are going to do a reboot there, and what that’s going to be we don’t even know yet.
Cast? What cast?
No, it’s so silly. We gotta get a story first. You can’t pick characters until you have a story. It’s a funny thing, it’s not… what I perceive Spider-Man to be is just a redoing of the whole thing. It’s not [that]. It’s an evolution, there’s still continuity that’s going on. There’ll be a lot of new cast, whether there’s anyone from the first we don’t even know yet. The truth is, there’s going to be a whole new story. The characters that will come along will be Optimus and Bumblebee, I’m sure.
Michael Bay took to his own website to say:
There has been a lot of speculation about what I’m going to do next and when or if I will do another Transformers. So let me set the record straight.
I have just concluded a deal with Paramount to do two movies, but it won’t be two Transformers.
I will first do ‘Pain & Gain’ with Mark Wahlberg and Dwayne ‘The Rock’ Johnson.
Then I will do the next Transformers for release on June 29, 2014.
