Ok so we know at the beginning of the movie, it takes place in Shanghai or a fictional city in China and the movie opens with Autobots and Military teaming up together shooting at Decepticon(s). One of which is a white Audi R8 which they chase. Involved in the chase are Arcee and the Twins. And then at the end of the movie which takes place in Egypt, they are fighting something MASSIVE. Could it be Devastator or The Fallen? Or both? Or will the Fallen take the form of Devastator?? Of course we won't know till we see some more. But it makes for some great speculative discussion.
