December 13, 2011December 25th sounds like a good estimate. For a very big anticipated motion picture they will release the teaser within the next few weeks to a month. I don't know why they would need to post pone it later. It would make perfect sense to release the teaser with the holiday films that are coming out around Christmas because a majority of people go to see movies during the holidays. "The Darkest Hour", "Mission Impossible", or even "Sherlock Holmes: A Game of Shadows" could contain the trailer for Prometheus. Some distributors wait until only months before the motion picture release of a film to let the audience see the trailer. But that mainly only applies to smaller scale films. You'd think they would want to get the word out early so more people are informed about its release. I have a feeling the Prometheus trailer will either be released this Friday with the "Sherlock Holmes: A Game of Shadows" or "Mission Impossible", if not those two then "The Darkest Hour".
