Yes, another one of those threads about TF4, but shut up and hear me out. I think the idea of having the next movie without humans might be cool, but I seriously doubt it would happen. The reason it would not happen is because people who are not into Transformers would most likely not even go see the movie if there was no human interactions with robots, drama, and of course a hot chick. With that said, I also remember Shia saying in one of the interviews that he's not sure he would be returning to another TF movie (if there was one) because there was nothing he could do for the character of Sam. Of course, Shia is just an actor, he doesn't make decisions or write the story. The way I think they could have him back in next TF movie is if he becomes a NEST soldier. In ROTF he didn't want to have anything to do with Autobots and Decepticons issues, however, in DOTM he's lost and doesn't know what else to be in life after college. Also, given that he has two Decepticon kills under his belt (Megatron and Starscream) well that gives him more bad-guy kills than some of the NEST soldiers. So, this opens a chance for a new chapter in his life where he becomes a NEST soldier and the story goes on with humans and Autobots hunting the remaining Decepticons on Earth. Shia is a great actor so he would be able to portray this new Sam. In the meantime, a new bad guy emerges and he wants to bring more Cybertronians to Earth to make it their home, since Cybertron is gone. Of course, this means getting rid of humans and keeping the planet for themselves and gives the whole story a conflict to work with. I think this would give writers a lot of flexibility to introduce some new characters, both Cybertronian and human. And just in case Rosie doesn't want to return to the next movie, they could write her off because she doesn't want Sam to be a soldier. I'm perfectly fine with her staying, but just throwing that out. Just pure speculation... What you guys think?
