I think if there was even an inkling of a new Transformers film, or a Reboot, moviebob would PROBABLY kill himself.
Peter Jackson or Chris Nolan might be good choices for it; as has been previously said about classic cartoon series', games, t.v shows, etc... the Director needs a preserved sense of childlike awe for what their directing in order to keep it close to the original, but branching off and expanding in a way that is believable.
This is clearly hypothetical in choice; the transformers movies need to stay dead, lest angry fans go on an decepticon killing spree
