One of the big pieces of news is that the Smuggler's Run attraction, where you get to fly the Millenium Falcon, will feature an audio animatronic version of Hondo Onaka, and yes he will be voiced by Jim Cummings in case anyone was worried.

Smuggler's Run is a fully interactive attraction where you fly the Millenium Falcon on a mission for Hondo.
There will be stores where you can build your own R2 or BB droids, and your own lightsaber.
Daisy Ridley, John Boyega, and Oscar Isaac appear as Rey, Finn, and Poe in Rise of the Resistance. The attraction also features a confrontation with Kylo Ren, but there is no mention of Adam Driver.
All of the food and drinks will be Star Wars themed, like Ronto Wraps, Meiloorn Juice, Felucian Garden Spread, and both Blue and Green Milk. They will offer both meat and vegetarian food, and alcoholic and non-alcoholic drinks.
There will be animatronic Loth cats.
The Play Disney Parks app will become an in universe datapad that will allow you to interact with the land.
Both Smugglers' Run and Rise of the Resistance will feature new John Williams music.
