Dances with Gnolls
Well again, the article and person they're quoting thinks actually officially de-canonizing the Disney films is unlikely, but that what might happen is they focus on the "Mandaloria era" and thus essentially ignore 7-9. They could then build up different regions of the SW universe and never have to refer to the events of 7-9, even if the timeline advances that far.
That isn't a huge ground-breaking prediction though. They have already said they are hoping to tell other stories in the Star Wars Universe. Many that will not revolve around Jedi, especially of a particular bloodline. What I can't guess at is how much they 'ignore' those newer episodes. That remains to be seen.
