In an interview with USA Today, the 49-year-old director said he will not be directing the robot-filled series that he has been directing since 2007 as he has other plans.
"There's kind of a new chapter, a new direction in movies I want to make," Bay said.
"I have a lot of stories to tell.
And it's about flexing new muscles."
It was also reported that actor Mark Wahlberg may not be returning as the main star.
The next Transformers film is set to feature a beast war when Optimus Prime leaves the Earth.
This means that the fifth installment of the movie series will feature a battle between the Autobots' descendants and the Decepticons' descendants, the Maximals and the Predacons.
Producer Lorenzo di Bonaventura has given some hints about "Transformers 5." In an interview with Screen Crush last June, he stated: "You know, Michael [Bay] has found a really great blend of real humor, integrating a lot of human characters with a lot of different kinds of Transformers. I think in that respect, it will be very similar."
"Transformers 4: Age of Extinction" has been one of the year's highest grossing films.
The upcoming fifth installment of the "Transformers" series will premiere in 2016. This means that the movie franchise is going back to its two-year trend.
Bay broke the trend with "Transformers 4: AOE;" there was a three-year gap between the third and fourth installments.
It is speculated that "Transformers 5" may be the lowest grossing movie of the franchise. While the last movie grossed close to $900 million worldwide, it earned only $243 million in the U.S., an all-time low for the movie franchise.
Maybe bring back Mega fox and Shia LaBeouf as the main stars.
who knows they could come back but i guess we won't know anything until 2016 gets here
