Trivia

 * It should be noted that Noble Six, at approximately 42 seconds into the trailer and during the invasion of an unknown city on Reach, that he/she is seen carrying a pendant. This may be an indication that one of his or her loved ones was in the city at the time of the invasion.
 * It should also be noted that the trailer is 1 minute and 6 seconds long, which is a reference to Bungie's love of the number 7, because 1+6=7.
