I just read the Vanity Fair issue about Star Wars, and one of the mistakes that the editor had to fix was that one article mistakenly referred to the upcoming movie as "Star Wars: Episode 7: The Force Awakens" when the title is actually just "Star Wars: The Force Awakens."

Past movies have all included the full title with the episode number - any reason why JJ Abrams has decided not to continue that pattern with the new film?
