Been traveling the past couple week, so didn't get a chance to post till now.
That trailer does look awesome. I really like the lead actresses they're finding. Mon Mothma looks identical to the actress who played her in RotJ, which is pretty cool. The AT-AT scene looks badass. And I loooove the slow, haunting Star Wars theme song played at the end. I hope the "spinoff" movies are a little darker than the main episode movies. Not that Force Awakens was too light-hearted, ala Phantom Menace. But some dark and gritty Star Wars content would be pretty sweet.
I heard a while back that they were doing a bunch of Star Wars-based movies alongside episodes 7, 8, and 9. Rogue One is just the first. There will be one focused on Han Solo in 2018 (the casting for that will make or break it). And one on Boba Fett in 2020.

Basically one movie every year for the next 5 years.
I'm with you -- doing some non-movie Star Wars stuff would be great, though I won't hold my breath.
