There's No More "Transformers" For Bay After 4th!

Before the fourth film has even began production, director Michael Bay has confirmed via Hero Complex that this will deffo be the last "Transformers" for him. This is what Hero Complex said, (The director, by the way, says that the fourth film will include some redesign of the robots and an entirely new cast. He also said it will be his last and set the franchise up "for the next guy.")  

.......... Bay said this about the third film too.
