I think the performance of their upcoming slate of theatrical Star Wars will determine the future of Galaxy's Edge. So they're holding off on porting it until they know what they want to do with it.
The new Rey film is a key one for this decision. If it bombs, they will likely go ahead with detaching the focus of GE from the sequels.
If the Mandalorian and Baby Yoda, Filoni Thrawn movie, are a success (despite requiring D+ TV homework) you can bet they will make GE set as timeless and feature characters from all over, rather than just sequels. Which is how it should've been, honestly.
We all know GE begs major changes, and they know it too. As a Sequel enjoyer, it's obvious that this is what they are thinking.
