TF4 Ambulance: Could it be Ratchet?

The ambulance that you can barely see in the Autobot group shot from a while back has reappeared and this time you can clearly tell it is an ambulance that actually resembles Transformers Prime's version of Ratchet. Could it be him? Thanks to Jorge R. for the photo. Also, check out some more photos from filming in Taylor, Texas below from @gametavern. You can see that there is going to be an Easter egg in the movie. Notice how the movie theater has Bad Boys and Pearl Harbor listed on the sign. Both are directed by Michael Bay. What's really interesting is that the number after Bad Boys seems to be a 3. Bay has been rumored to direct a third movie for quite some time.
Note: Since there are so many on-set photos, I will not always post them here. I will often post more on Twitter, so make sure to follow @TFormersNews.
