bumblebee face revealed

Bumblebee pops on out to say *hi* [via]and then there's also the video footage of the filming of a Transformers street sequence featuring Jazz (Porsche) and Ratchet (Hummer) in vehicle-form [via] = which i can't view at all! (but doesn't mean you'd not get to too, innit? *heh*)and then im wondering if either Autobot or Decepticon have any "mouths"? or at least a semblance of a "moving orifice"
