According to iO9, It was announced at Star Wars Celebration in Orlando this weekend that the planet Crait, seen in the new Star Wars: The Last Jedi trailer, will become part of Star Tours later this year.
Both Disney Parks are currently undergoing their largest expansion in history as a dedicated Star Wars Land is under construction at both Disney’s Hollywood Studios in Orlando and Disneyland in California.
Disneyland has been running a promotion called Season of The Force for the last couple of holiday seasons.
However, you won’t need to wait until 2019 when the new parks open to get your first taste of brand new Star Wars material.
