I didn't notice this until last night, but when the pillar is destroyed and Cybertron is being obliterated all of the Decepticons, warships, etc are sucked back up through the space bridge. Why? None of them came from Cybertron, they were all on the moon. It makes no sense they would all just go away at that moment. Also, random observation: When Not-Wheeljack Transforms in Chicago the front part of the car is fairly quick and then he kind of rests on his arms as the rest of him slowly transforms.
