Maybe this is the best strategy for Disney at this point...
Make one more Anthology movie that ties up the loose ends that they stupidly left open at the end of Solo, then just take a break (that'll be the end of this Han Solo storyline that no one asked for). Let the fans recuperate from the damage of The Last Jedi, and spend that time drafting a story that is actually coherent and relies on a strong story and characters rather than social justice messages and fan service, then in 2023-2024 or so then release Episode IX. Right now we are being bombarded with crap, they need to go slower and put more time, thought and creativity into these movies.
