What you see here is a mystery silhouette marked Optimus Prime. But, it seems to have a few more points on it.

Since we’ve learned the possibly huge Transformers rumor about Optimus Prime isn’t so possibly huge, because it appears that Optimus Prime combines with Jetfire, who was officially described by production as “a villain whose age and broken-down physicality leads him to help the Autobots.” Jetfire, as his name would suggest is an SR-71 Blackbird, and explains what production was doing at the Smithsonian Air and Space Museum last June:

To explain how the two relate to each other, and how Optimus Prime being out-fought might not mean it’s over, a YouTube toy review:

Another one of these silhouettes, blacked out key chain designs so we don’t know who is who, is “New Character:”

And no one seems to have any answers as to who/what this new character is and the purpose of a new character in a film we already know has two formidable villains in Devastator and Fallen.

I did recognize one thing about the silhouette.  This is certainly the giant bot that’s holding Sam (Shia LaBeouf) down on top of the car in the trailer:

The ends of New Character’s claws have tiny clamps on them, all the better for holding down tiny, pesky humans.
