Only Harmy can say for sure, but he has said he’s not likely to do an all-film-sourced DeEd, because at that point, lots of others could do that work (although I’d personally still encourage him to go for it, because he has demonstrated solid skills beyond despecializing). I expect we’ll see something more like Jedi 2.5, where lots of pure film footage was mixed in, but only where it blended well with the surrounding footage. I’m sure film sources will be heavily used in despecializing Blu-ray footage though. Complete lack of GOUT is a pretty safe bet though.
