The question will be if these characters go beyond EP9. Rey, Poe, and Finn likely will. Kylo maybe, we'll see. So if Kylo continues beyond EP9 they'll likely have to update the land to remain in continuity, or else unofficially say the land is stuck in pre-EP9 continuity.Well not necessarily. There is only one episode left in the Skywalker saga. So if Episode 9 doesn’t really alter what they have going on in Galaxies Edge then they re kind of in the clear.
