A while back in an interview, Michael Bay said that "something bad has happened to America"... and that got me thinking. Now, with new photos released of destroyed streets, and reports of extras acting as refugees from an alien invasion has prompted me to post my theory. I think that the Decepticons have invaded and taken over America. Like, complete alien invasion. They've attacked cities, military bases and various human settlements, reducing them to rubble. I'm kind of thinking that the "refugees" will be kind of "War of the Worlds" styled, with giant alien robots killing them all, and destroying all their cities. We know that the Decepticons are indeed targeting humans this time, so why not? Obviously, this would happen later in the film, not the beginning, but I think it's a cool idea. I'd love to see a "War of the Worlds" type thing going on, but with Transformers instead of tripods.
