Details on Michael Bay's Transformers 4 have been scarce.  We know that it will be a reboot of the series, none of the original cast will return, Transformers 2 and 3 writer Ehren Kruger is penning the script, and the robots might be front-and-center as opposed to a human character.  Today, the 24 Frames adds a new piece of info to the pile by reporting "the fourth film will include some redesign of the robots."  24 Frames also confirms that the new movie will have an entirely new cast.Furthermore, Michael Bay says Transformers 4 will be his last entry in the franchise even though that's what he said when it came to Transformers 3.  His goal with Transformers 4 is to set up the series "for the next guy."  So rather than letting a new director completely spin a new Transformers tale, Bay will make sure that future directors will still have to hold to his template.  Classy.  Transformers 4 is due out June 29, 2014.
