Yeah, Luke and Leia went to Jedha in the new Marvel comics, so it’s not completely uninhabitable.

Here were the set photos taken back in October.

Jason Ward actually mentions how Jakku was originally going to be filmed in Jordan before Abu Dhabi gave them a better deal. But then after that didn’t work out, Rogue One shot there for Jedha.

Ward speculated that they might go back to Jordan to film it as maybe a different part of Jakku since JJ originally conceived the planet looking like Jordan. Although I wonder that since the Jordan landscape was established with Jedha already, that he would go back and use it for Jakku too.

The poster does mention seeing a lot of tents and speeder bikes that look similar to Rey’s speeder. So the tech might seem to point more toward Jakku. Though the alien cut outs standing out in the desert also gives me a pilgrim vibe. Though the fact we’ve never seen this kind of alien before makes me think it could just be a new world.

Then again, we really don’t know how much Jedha might have changed in the past 30+ years. But to me, the landscape definitely feels more like Jedha than anything else. I could see then going back if the rumored McGuffin of the film is Jedi/Force related. What if the McGuffin was the Journal of the Whills?

Definitely fun to speculate about!
