From what I've heard, there aren't any plans for 트랜스포머 4, since everyone was so busy with Dark of the Moon. However, if there is a fourth movie, chances are:
-It'll be the start of a new, 초 trilogy -Steven Spielberg might be the director -Michael 만, 베이 might make a return if the project isn't rushed
I heard that they might make another 트랜스포머 movie (the 4th one) where the story is about cybertron and how there came to be to seperate teams autobots and the decepticons but now ther story is about the 3rd and how they caused war between the decepticons and the autobots.... ask if u want to know more........
