I hope they keep the first movie's theme tune for this film, the one when the title appeared, or when we first saw the Enterprise in spacedock etc...
Well they used it in the 9 min preview thing, so unless the movie version uses different music ( though I doubt they would) it's in there at least once. Besides I do think they reuse theme tunes in sequels.
I think I heard that the music on the 9 minute preview was supposed to be temporary, since Giacchino hadn't started work on the soundtrack yet. So it might end up changing in the final film.
Though I did like the tune in the Mickey scenes.
