Transformers: Devastation Behind the Scenes with Peter Cullen Trailer

Peter Cullen has voiced Optimus Prime on and off since 1986, and with almost 30 years on his tab he still enjoyed voicing him for Transformers: Devastation.

There is a little new footage, which might help answer the question we've seen most often -- can you drive around normally, or are transformations only for fighting combos?

The answer seems to clearly be 'yes, you can transform and drive around'.
