Update: Three new pieces added. The main one is the animated gifs created by John R. (thanks!) that highlights how the scenes have been altered in the month since the Super Bowl trailer and this trailer with alterations to face shape, more details, change in lightning, more particle effects and other details that you might not catch but add to the "realism" of the moment. In addition has added links to sites with screen captures from the trailer. Finally if interested downloading the trailer, MichaelBay.com has the link.
