This was a trailer for an upcoming teaser. At the very end it says "Watch the teaser on December 17".
As with the marketing of 'Dark Knight' and 'Dark Knight Rises', the first 9 minutes of 'Star Trek Into Darkness' are going to be attached to IMAX showings of 'The Hobbit'. This footage was shown to the press a couple days ago and has been getting mixed to good reviews in comments that have leaked out. Folks admitted to not being blown away by the opening scene, but seemed much more excited by quick cuts of other scenes from the movie.
The newer (longer?) trailer should be on line in a week.
