Here's a new photo of another vehicle redesign for Transformers 4, and this one gives us our first look at Optimus Prime's new design. Michael Bay previously said that he was going to deliver all new robot designs, and as you can see, he's followed through with his word. That's one burly big rig! Bay describes it as a "completely upgraded, custom-built Optimus Prime from Western Star (a subsidiary of Daimler Trucks North America)." I'm looking forward to seeing what the robots end up looking like.
The movie also stars Mark Wahlberg, Jack Reynor, Nicola Peltz, Stanley Tucci, Kelsey Grammer, Sophia Myles, T.J. Miller, and Li Bingbing. We're still waiting on official story details, but the movie comes out in theaters on June 27th, 2014.
