There have been strong rumors that we’ll see a new Behind-the-Scenes “Sizzle” at D23 much like Rogue One got at Celebration last year, and now others are confirming that it looks to be the case. Collider has heard the same thing, nothing at SDCC but a BTS reel at D23 Expo:

As for where the 90 second trailer the BBFC recently classified will pop up, that’s a mystery. It’s possible Lucasfilm will show that on some television event in August like they did with the second Rogue One trailer last year during the Olympics. Possibly right before Force Friday in early September.
