You guys put far too much weight into the Story Group. They’re mainly there as advisors. The two that do the most heavy lifting are Pablo and Leland and they just ensure that whatever a project’s director/writer is doing is consistent with the established lore. And there they’re fairly powerless. See: the Starkiller’s carnage being seen from Takodana and Holdo’s last stand. There is no grand road map, they’re just doing things project to project.
I think this is correct. They’re mostly there just put their stamp of approval on what the writer/director comes up with. I think it’s pretty clear there isn’t a road map for these films and there’s no way that J.J. “Mystery Box” Abrams had a plan for how the loose ends he left in TFA would be tied up.
