Below is a gallery/video of images from transformersfrreak1007 at Playa Vista in Los Angeles where Transformers 3 is reported to have setup shop. The video mentions Loyola Marymount University which is a direct neighbor of the studio based on Google Maps. Transformers 3 wise not a whole lot is shown. You get a look at maybe Ironhide, the Ice Cream truck and its halves just sitting in the lot from Revenge of the Fallen and the office tilting setup from the other day. The last images are of a rusted lunar module that may or may not be Transformers 3 related. The film is shooting at the Kennedy Space Center in September but don't really have enough information to assume a link. Thanks to Katie for finding the video.
