Of course, even knowing that Star Wars Episode IX is returning to this location is no guarantee that the plot will return to Yavin IV.
The hanger is little more than a large enclosed space, and that’s good for filming lots of different things.
A change in set dressing and a few careful camera angles and the movie can make the same place look like somewhere totally different.
It could be a large hanger at Black Spire Outpost on the planet Batuu, the location created for the new Star Wars Galaxy’s Edge at Disneyland and Walt Disney World which has been referenced in the films and will almost certainly be used as a location in one of them eventually.
