"We have great respect for the dialogue and concern being expressed around Confederate,"  HBO said in a statement last year. "The project is currently in its infancy so we hope that people will reserve judgment until there is something to see."

There's been no march forward on the project, and as Deadline notes, Benioff and Weiss are now set to write and produce a new series of "Star Wars" films. The daunting task presumably leaves little time to develop other projects.

“We are honored by the opportunity, a little terrified by the responsibility, and so excited to get started as soon as the final season of Game of Thrones is complete,” the two said in a joint statement regarding the new "Star Wars" gig.
