An ABC listing confirms a 3-minute trailer for Rogue One: A Star Wars Story will be broadcast on 15th July. That's according to Making Star Wars.
This coincides with Star Wars Celebration Europe where director Gareth Edwards and Lucasfilm president Kathleen Kennedy will headline a Rogue One panel. It's expected the new trailer will premiere during the event.
Despite the much-publicised reshoots, which isn't unique to this movie, I can't wait to see Darth Vader back on the big screen this December.
