Sorry to bump an ancient thread but I thought it might be a little early to start the Star Trek 2 thread.
Star Trek 2 has a tentative release date of
June 29th, 2012. This specific date was chosen because of its proximity to the 4th of July weekend in the US.
Originally Paramount had hoped to release it in Summer 2011 but that meant it was unlikely that JJ Abrams would be able to return as director due to a busy schedule. Moving the movie to Summer 2012 increases the chances Abrams can return in that capacity.
