Why It Was Cancelled

 * Erik Aadahl as Bumblebee
 * John Goodman as Hound
 * Ken Watanabe as Drift
 * John DiMaggio as Crosshairs

 * Jim Carter as Cogman

Decepticons:

 * Frank Welker as Megatron

Others:

 * Gemma Chan as Quintessa

Results

 * The 2018 film Bumblebee was originally going be the last film in the Michael Bay series, but it was soon changed to reboot the franchise.
 * Hasbro now no longer wants Michael Bay to work on the upcoming films, so the story was changed entirely and the Transformers will be redesigned.
 * Two reboot films are in development, one of them is an untitled Bumblebee sequel, an animated film and a new live-action film.
 * The next live-action Transformers movie is coming in the Summer of 2022, but it is currently untitled and will not have Michael Bay at the helm.
 * There is also an upcoming animated Transformers film with Josh Cooley (the director of Toy Story 4) at the helm and will focus around Optimus Prime and Megatron on cybertron.
