I honestly think Hasbro is going to try extremly hard to keep micheal bay on board for TF4. even at the extent of over paying the guy. perhaps it's not a money issue for micheal bay. doing those TF live action movies takes too long. micheal bay seems to want to not just be known as the director of TF movies. micheal bay wants to expand his resume himself by doing other movies. Deep down inside micheal bay has hinted that if he keeps doing more TF movies. then they'll eventually bomb & ruin his credabilty as a decent director. micheal bay seems like the guy who gets off a sick horse before it dies. If Micheal bay quits after TF3,what will happen next? I'm seriously thinking after TF3. The next TF live action movie will be a total re-boot. different human characters characters,different settings,diffferent stories. some of the robots will have the same name but not the micheal bay TF movie personas. If it's a total reboot,I highly doubt TF4 will happen in 2013. most likely TF4 will happen around 2014 or my solid guess 2015. Many are assuming,Hasbro will simply hire a new director. then hasbro will continue with the established story. use the same human cast & same robot cast. PROBLEMS ARE AS FOLLOWS: (1) Usually movies that keep switching out directors. never do well & are just horrible. Hasbro seems to study various researched reports. examples: star trek movies,terminator movies,superman movies,etc.... (2) Didn't hasbro enter into some binding contract with micheal bay. giving micheal bay some controlling interest on the characters,stories & designs he helped make successful on the First 3 live action TF movies. (3) I may be wrong on this one. but didn't micheal bay help create that CGI company,special effects & sound stuidios that uses all the CGI images/robots in the 3 live action TF movies? (4)Without micheal bay & his camera crew,TF4 won't look like it belongs in the same movie verse. Micheal bay has stated on occassion he uses the most exspensive & advanced new age cameras,lighting & talented crew. (5)isn't hasbro finding it hard to have TF1 & TF2 live action movie toys as botcon convention or club exclusives. so someone out there apparently has controlling interest in thec live action TF movie toys,perhaps CGI Movie designs,perhaps established live action human cast & so forth. is it micheal bay? is it dreamworks? is it steven spielberg? is it the CGI company? nobody knows for sure because all of this info is classified.
