act on instinct said:

Always in motion, is the future. I expect plans to change depending on how audiences respond, it’s all concept until it’s out. Studios generally aren’t very good at planning ahead, all cautiously about the next move. This franchise business and nu-marketing strategy of “phases” and “cinematic universes” is a gamble, they throw out that slide with a decade of projections, it’s all just smoke and mirrors until it’s made, and this ~~administration~~ studio has unarguably had a bit of a revolving door of creatives being shuffled in and out, with possibly just as many projects canned as have been announced (haven’t done the math, not sure if that checks out) or end up being restructured.

Out of curiosity I kind of want to layout creatives that have been involved with projects, and which projects were canned or heavily restructured.

COMPLETED
The Force Awakens - JJ Abrams and Co-Writer Larry Kasdan
Michael Ardnt also got writing credit, but he left the project after he couldn’t deliver a final script in their timeframe.
Rogue One - Gareth Edwards, Story Gary Whitta and John Knoll, Screenplay Chris Weitz and Tony Gilroy
Tony Gilroy replaced Gareth for extensive reshoots and the film was heavily restructured. It seems early cuts were just not what they had envisioned, but did not have any issues with Edwards himself.
The Last Jedi - Rian Johnson
Ironically to some fans, I’m sure, the film project with the least behind-the-scenes drama.
Solo - Ron Howard, Writers Lawrence and Jon Kasdan
Ron replaced Phil Lord and Chris Miller as director and the film had extensive reshoots due what was reported as a very improv approach with their direction.
The Rise of Skywalker - JJ Abrams and Writer Chris Terrio
Abrams and Chris Terrio replaced Colin Trevorrow and Derek Connoly as director and co-writer respectively. Reported reasons vary from drama with Trevorrow, backlash from his film Book of Henry, and Colin not being able to rework his script after Carrie Fisher passed away.
The Mandalorian - Jon Favreau & Dave Filoni
No reported issues that I’m aware of during production.

KNOWN FUTURE PROJECTS
Cassian Andor Disney+ Series - Showrunner Stephen Schiff, Co-writer & director Tony Gilroy
Seems to be moving forward but no recent news or projected release date.
Kenobi Disney+ Series - Director Deborah Chow, Writer Hossein Amini
Set to release 2020.
[note: apparently Disney is planning to focus on new Disney+ series in the coming years, so we may hear of more rumors or pitches in the future.]
Rian Johnson film trilogy - Still in early-stages of development with no known release date.
Kevin Feige film project - Also in early-development stages with no projected release date.

SCRAPPED PROJECTS
Boba Fett Standalone Film - Director Josh Trank
Cancelled after Trank’s Fan4stic debacle and other personal issues.
Kenobi Film - Director Stephen Daldry, Writer Hossein Amini
This seems to have been cancelled and adapted as a series due to Solo flopping, no issue with the director or writer.
Mos Eisley Cantina Film - * Rumored Director* James Mangold
Making Star Wars reported this film had studio space reserved for it at Pinewood. It also was apparently scrapped after Solo flopped.
Potential Solo Sequels - This may have only been a hope for Jon Kasdan and never officially planned.
Benioff and Weiss film trilogy/series - Benioff and Weiss reportedly left the project due to their deal with Netflix, but it is possible Lucasfilm had lost interest due to Game of Thrones backlash.

Let me know if I have made any errors or left anything out.

EDIT: The “hiatus” state of the Feige and Johnson film projects has been moved into “Known Future Projects”.
