In a recent edition of the podcastHumans From Earth with Geoff Boucher, Orci says the film will be more like the original 1960s series than the previous two movies with the crew now out of the prequel phase and onto their five-year mission. It also means a lot less time on Earth next time out:
"In [Into Darkness] they set out finally where the original series started. The first two films - especially the 2009 [Star Trek] - was an origin story. It was about them coming together. So they weren't the characters they were in the original series. They were growing into them and that continues on in the second movie.
So in this movie they are closer than they are to the original series characters that you have ever seen. They have set off on their five-year mission. So their adventure is going to be in deep space... they are in deep space now, so lets see what's out there."
