The worst part of this news is finding out there is an entire rian johnson trilogy.
The best part of this news is that david benioff will have no involvement.

Pretty sure this is the story arc Benioff and Weiss were working on, it was supposed to take place in the past before the prequels but not a KOTOR type thing so 400 years in the "High Republic" era matches up pretty much spot on with that. So likely they do have "involvement" if its based on their idea/concept.
