I wouldn’t be at all surprised if Jedha turned out to be the birth world of the Jedi Order . . .
Isn’t that supposed to be Luke’s unpronounceable archipelago planet from TFA, though?
EDIT: I don’t feel like tracking down the video, but it looks like Donnie Yen let it slip that the Jedha-Jedi connection may have something to do with constructing lightsabers. I’m thinking crystals? Although there was already that Clone Wars ice planet.
