They showed a behind the scenes video with more concept art from the land. Much of the aesthetic seems to be a sci-if Harambe mixed with IOA's Port of Entry of sorts. VERY brief shot of Big Bird testing.
More backstory on the planet itself. Used to be thriving and vibrant, but has fallen from grace a bit and has become a haven for the more "interesting" crowd.
New concept art for live performers. So far, all humanoid aliens/humans. Interactive details in the land itself, but nothing indicating guest triggered "Force" interactions.
"We're gonna be using rooftops, ladders; you're not gonna be sitting in a chair passively. Things will be happening around you."
New droids with their own personalities. You can help the Resistance OR the First Order through interactions in the land.
"You and your flight crew will pilot the Millenium Falcon." You won't be able to fail your missions entirely, but you do have control and there will be consequences if you don't fly well.
There will be more than two AT-AT's.
