posted an official staged image that shows some of the cast and crew posing in front of some obelisk. The caption with the photo just identifies the men in the image, "Pictured left to right: Jack Reynor; Mark Wahlberg; 2nd Assistant B-Camera Casey “Walrus” Howard; 1st Assistant B-Camera John Kairis with back to camera; B-camera Operator Lukasz Bielan; Director Michael Bay; and Director of Photography Amir Mokri.

posted photos from the TF4 set at The Hyatt Regency McCormick Place that red taxis and other vehicles with Chinese characters that fit a lot of the props from Detroit so it seems that more from the Hong Kong, China setting is being filmed. Last, is a link bait article from Superherohype claiming that today's filming involves the Dinobots. That's it. Absolutely nothing to support the theory so take it with a grain of salt.
