So, I believe I heard a breath like noise at the end of the credits, playing along with the Paramount logo. Others have said they heard the same thing. I personally believe this was done on purpose, as a very slight reference to UNICRON in future Movieverse movies. With all the Bay leaving, etc etc talk - that could make no sense to put a future teaser in. However, IMO, I heard something, and it makes no sense being there otherwise. So, for those that stayed all the way to the very end, and saw the Paramount logo after the full credits, and payed attention (aka wasn't getting up, talking, on your way out, etc) - DID YOU HEAR SOMETHING TOO. And what do you think it was. Later! Update (from me personally): I just popped into the end of the movie again, waiting for mine to start. There is definitely a sound. However, this go around it was more of a robo whine, like what plays at the start. Less bass in here. In that context, I can see it just being a sound to close out the previous song and conclude the credits. So - breath, no. Sound, yes. I think.
