Wheeljack Revealed?

An unofficial Transformers Dark of the Moon Facebook page has posted the below picture that could prove that the alt mode of Wheeljack is the blue Mercedes-Benz E550. The pic on the left is a panel from the comic book adaptation. From the comments, the image on the right is about 45 seconds into the trailer when Optimus enters warehouse talking about the "grave mistake" being made. There isn't enough detail to verify if the head matches "Einstein." Thanks to DJ.Bigtyme Beats for the link.
