From Disney's PR regarding the D23 Expo:
Star Wars: Galaxy’s Edge
This highly anticipated new land is set to open in 2019, both at Disney’s Hollywood Studios and Disneyland Park – on a grand scale – including the creation of a full-sized fleet of X-wing star fighters and a life-size Millennium Falcon starship.
The totally immersive land will include two jaw-dropping attractions that allow guests to have control of their experiences. One attraction will put guests in the middle of a battle between the First Order and the Resistance—inside a Star Destroyer. In the second attraction, guests will have the chance to fly the Millennium Falcon – the most famous ship in the galaxy. Throughout the land, guests will also have the chance to interact with Chewie, the lovable BB8 and members of the First Order, plus wander through a toy shop in the street market run by a Toydarian, one of the creatures from Star Wars: The Phantom Menace.
