Bumblebee might just have a third vehicle form in Transformers 4. A yellow Volkswagen Beetle was spotted on the back of a trailer with the G1 looking Optimus Prime truck. The truck is not confirmed to be Prime, but the truck is almost an exact copy from G1 with the white stripe, plus it has flames. Could the Beetle be Bumblebee, or could it just be an Easter egg like in the first Transformers movie? As a side note, it looks like this video was recorded in Texas.
