TFW2005 found eBay seller "antear" has posted many auctions that covers pretty much every Transformers that will show up in the upcoming movie. It also includes to movie stills. If look at some of the designs, the names have changed a little such as Brawl and Barricade indicating these sheets are from last year pre-production plans, but the overall designs seem to match pretty closely recent pictures of some of the Transformers, especially the toy designs. It makes me think that these are the either the final designs or just a version away from being them. Sorry for the size but I guess the eBay seller wanted to make sure people would buy them.
This is a long post with many pictures some of which are repeats from previous posts. I am going to start with what is the best of the lot in my opinion, and whoever is putting the next trailer together, a sequence with this kind of image needs to be in the trailer. It helps to drive home that we are going to be watching a live action Transformers movie.
