To my ears it sounds like a bunch of different ques that have been cut together, not one piece composed as a whole. Indeed that's almost never the case with trailer music anyway. 99% of the time trailer music is either from the movie itself, tracks from the temp score or a needle drop.
Needless to say that last option is out of the question and since Star Wars trailers can only really use music from other Star Wars movies if the new score isn't ready yet, and given that this is obviously a new composition, it's almost certainly from the movie. Or at least the early work on the score before they start dialling it into the final edit.
