Trailer technical notes I've picked up
Kylo hangar scene:
First order still uses AT-AT and AT-ST along with the new Gorilla Walkers
Shuttle being used as a observer?
Gorilla walkers about 2x larger than AT-ATs
Storm troopers can walk on still cooling lava, I guess ceramic armor has its advantages :-p
Rey is holding that lightsaber awfully close to the emitter...
Kylo has a tattoo/tech bandage for his scar, I was hoping for a half mechanical face shield
Rebel fleet is on the run from the Supremacy, strongly hinted that Kylo is going to take out the command bridge that looks like it similar to the Mon Remonda from the old essential guide to vehicles (nice retro targetting screen that has no bearing on the current orientation...)
Rebel fleet seems to be focused on the Raddus-Class Pickleship (a few KM, looks like a nice combination of Home One and the McQuarrie Mon Cal concept cruisers)
Narrower ship exploding that looks more like a lengthened gallofree or something like and MC30c
two other ships in the escape shot, a very asymmetrical frigate with tiny tiny engines
also another ship in the background that looks like a saucer with two 6 engine corvette blocks on the back, might be pretty big given how it is shown, maybe 500m?
many many instances of bubble shields around the rebel ships
reverse shot with Kylo doing strafing run, Supremacy in the background, maybe 4 or 5 unidentified mon cals that are similar to the ones destroyed by the starkiller in Force awakens
I really want the big clicky button on Kylo's control yoke, it probably makes a very satisfying mechanical noise when pressed.
Obligatory for new Trilogy "fly through a ship scene" (Stop it J J, you aren't supposed to work on this movie)
Chewie looks a little too shiny, hopefully not CGI
Porg human teeth are scary, especially the lack of an upper jaw, once you see it you can't unsee it.
Poe in what looks to be escape pods (low ceiling, not sure why the observation windows but they are getting massacred.
Xwing with a booster jet... not really sure why this is needed, but maybe to Awing the Supremacy Command Bridge? Multiple New Order SD's in the background
Xwings blowing up surface greebles on Pizza slice DumbNought... seriously why even have anti star fighter lasers the size of office buildings if the star fighters are just going to blow them up. At least the Death Star lasers were designed to be anti capital ship and the fighters could fly around them...
Bombers aren't using their ball turrets vs ties... why have defensive lasers at all?
Pizza Dumbnought has really weird thrusters, looks like 70's style turn signal lamps
last scene is heavily implied to be linked together, but the lighting is very different.
