Re: What villains are left for a 4th film?
If they are lowering the budget as Bay said, we aint getting Unicron, simple as that, personally I now thin Thunderwing would be even more appropriate as he is powerful enough on his own to take on a large group of TF's. They could and should go back to Cybertron for some of it as well.
