But.... what about the Bothans?
Seriously, the ruined Jedi statue in the sands of Jedha was a great touch. It helps establish Jedha as this ancient place that was sacred to the Jedi Order. Funny though, the hooded figure of the Jedi bore a strong resemblance to ANH era Obi-Wan.
I was also able to find Moroff by going methodically through the trailer. And it turns out that he's in the scene on Jedha where the AT-ST is attacking the Rebels.
Seeing some of the Rebel Starfighter corps in action was cool. It looked like they might have been attacking some sort of orbital shipyard, along with some capital ships in support. I'm pretty sure I saw at least one ship that resembled the ones that Leia got to the Rebels in her season 2 appearance on the REBELS animated series, along with some Nebulon cruisers like the medical frigate from TESB and ROTJ. And I think the blue flightsuits are pretty cool, too. The night scenes of the ground attack by the Y-Wings and X-Wings was a great visual as well.
Given the flashback scene, I have to wonder... did the Death Troopers follow in the footsteps of the Republic Commandos? They seem like they might be an evolution from those particular Clone units.
