Another thing thing that I noticed in the trailer;

I feel like a lot of the film is going to take place on Jedha. I aslo think it’s interesting that the DS apparently goes to Jedha (hence the eclipse). There’s a shot in the trailer of Jyn and Cassian flying away from huge explosion so there might be a scene where the DS actually attacks Jedha. Of course it’s not referred to as “fully operational” until the events of ANH, so I guess this scene might show us what the unfinished DS superlaser is capable of. This also implies that the shot of the DS that was posted earlier, which I said looked up-side-down, is probably it aiming down on Jedha. The shots of Krennic with the view of Jedha I’m assuming is him ordering it to attack.
