There will definitely be a version 2 of ESB and ROTJ (well, I'm definitely planning to make them anyway). I just watched ROTJ the other day and while yes, I'm quite happy with most of the despecializations, the compression artefact are really ugly and of course the BD source should help get rid of the crushed blacks. And yes, the slowed down shots will definitely need a redo (btw. it was You_Too, not me, who slowed down the shot of Han before he shoots). I'm also not too happy with Sebastian Shaw's eyebrows restoration, there a distracting shake. Though I'm not quite sure I'll be able to fix that, maybe someone more skilled than me (or with better software) could stabilize both the original and the SE footage to be perfectly still and then I could just add the original camera movement back. And I may give the Rancor another shot.
In ESB, a lot more of those cropped cockpit shots were discovered later, so I'd like to unzoom those. Also, with Puggo Strikes Back, I might be able to put back some of the Hoth battle shots and Falcon approaching Cloud City shots that were recomped, which I didn't put back before because I didn't have a good enough source. And again, with the BD source, the crushed blacks could be fixed.
