Michael Bay has revealed another Transformers 4 vehicle via his official site, and we may just know which character this one is the disguise of! The Freightliner cab-over truck is quite possibly Optimus Prime's "brother", Ultra Magnus. Check out the pic after the jump..

Is this a sign that Ultra Magnus will feature in? Well, the truck above certainly resembles the character when in vehicle mode, and sports a similar paint job. Ultra Magnus (sometimes depicted as Optimus Prime's brother) is an Auotobot who first came about in the form of a repainted Optimus Prime toy back in 1986, and has since appeared in various incarnations of the comics and animated series. Of course we don't know for sure if this will be Magnus, as the only description given on the site is:What do you think?
