Bear with me if this has bee mentioned before. This is my first post EVER on these forums, although I have been coming to the site for months now. I heard the G1 transforming sound effect in the new trailer...it made me smile =) However I noticed it only did it when Optimus transforms. Is he the only one that will carry this sound effect in the film? Was it only used in the trailer? Will only autobots use the sound? Gahhhh so many questions! I remember reading a guy's review of his test screening and he mentioned that the G1 sound effect was in full force, however when we see Megatron, Blackout, Starscream, Bumblebee transform in the trailer(s) we don't hear "the sound". We hear clinking metal parts and whatnot. I hope Bay and his team decide to leave it in the movie, and make it more prodominant. I know Bay wants "realism" but at the same time...these are fucking Robots that transform into cars...they can have that sound effect and not hurt his view or direction.
