Addendum - I neglected to note earlier, the movie was delayed to December 2019. Previously, it was late May 2019. Unless the Han Solo movie gets delayed as well - and I can't assume it won't - it would be the only Disney-era movie to be released in May so far.
In what can only be called a safe choice, StarWars.com posted the article J.J. Abrams to Write and Direct Star Wars: Episode IX. Colin Trevorrow was recently ousted from the film, one of at least four projects encountering significant upheaval in the Star Wars universe over the last decade. Surely there's a non-disclosure agreement keeping us from knowing the full details of what happened here - or Josh Trank's movie, or Star Wars Detours, or the Han Solo film which is supposedly coming out in 8 months and has no name or no trailer - but I look forward to eventually hearing the full story on this tumultuous era of Star Wars.
Because things are fine, StarWars.com posted A Statement Regarding Star Wars: Episode IX. Director Colin Trevorrow is out, after directing Jurassic World and Safety Not Guaranteed (largely positive) and the new Book of Henry (largely negative.) A key quote:
"Lucasfilm and Colin Trevorrow have mutually chosen to part ways on Star Wars: Episode IX. Colin has been a wonderful collaborator throughout the development process but we have all come to the conclusion that our visions for the project differ."
No new director is known, but at this point I'd start putting money in big names and former Lucasfilm collaborators.
Variety has a big story on a bunch of new movie release dates from Disney. Of particular note, the as-of-yet untitled Episode IX has been given a date of May 24, 2019. For those of you keeping track, the as-of-yet-Untitled Han Solo movie is set for May 2018 (still), and that's only 6 months after The Last Jedi hits theaters in December of this year.
We don't know exactly why they're changing seasons for Star Wars, although it might have something to do with getting the heck out of the way of Avatar sequels or positioning Star Wars to take over for Marvel, which may be undergoing a retool of its own. Indiana Jones 5 was also delayed to July of 2020.
From a toy business perspective, this could actually be really good news for Star Wars fans.
