New Transformers Age of Extinction theatrical trailer reveals fire breathing Grimlock

New theatrical trailer for Transformers Age of Extinction is out. "This is not war. It's human extinction," says Optimus Prime in the trailer. But my favourite line is when Optimus says they need a new army and out comes Grimlock! Not sure if I've ever seen a fire breathing T-Rex but hey this is a Michael Bay film so what the heck! I can't wait for Transformers Age of Extinction! Screen captures here.
