Little bit of Transformers 2 toy line news with info on the voice changer helmets and Ultimate Bumblebee. The Optimus Prime helmet will have new lines, a transform sound effect, and damage paint. Since Hasbro is producing a Bumblebee helmet, I guess that means voice of Bumblebee, Mark Ryan, will have more to say in the sequel and indicates a possible retirement of using the radio to speak (a production money saver, since permission and money required for every bit used).
Ultimate Bumblebee will return, probably in his $80ish price range. There is an indication that his head is getting a new mold or at the very least they are adding the face guard. It’s hard to tell from the image but I imagine his body will be modified to match the production version of the Chevy Camaro.
