hey ppl will there be a sequel 4 transformers3???if so what will be the storyline????

maybe depends how this new one ends. Going on the trailer looks like this is the final battle

Probably the Unicron storys

I hope not. Transformers 3 is enough. A sequeal to that would just make it ew (no offense Bay)

They can make fourth and even five but all depend's who is willing to make it ^^ Michael Bay and Shia said this is there last Transformer's for them and they want to take rest from the movie serie's and work on some other project's.On the other hand Spielberg said he might make the fourth one whit Jason Stahnam in the main role which is kinda ridicilous because Jason can kill the Robot's by himself he doesnt need the autobot's ^^
If you asking me the best thing to do for now is to take the rest and to make another Transformer in about 3 years from now and to try Bay to get back Megan in it.Doing now another Transformers movie in a hurry whit different character's i think it's gonna be pure bullshit esspecaly in the main role if it's Jason Stahnam who look's like a Terminator and he can blow the fuck up the Robot's by himself ^^ about story's for the fourth part they can put Galvatron story also ^^
