It's possible. If they are going to finish the deleted scenes, then they will have to clean them up. There wouldn't be much to finish, actually; the Wampa scenes were abandoned and don't have the live-action material necessary to complete them, the Anchorhead scenes don't require further work, as does the original Cantina edit, while the sandstorm scene already had a matte painting completed for it before it was cut, and the opening Tatooine deletion was fully scored, edited and had VFX composited. The remaining deletions are just snippets of dialogue here and there, like the ones seen in Empire of Dreams. So I guess they could be finished--the sandstorm scene never had the dialogue recorded so even if they include the matte painting and do the one composite it needed, the scene will be still unfinished.

I would like for them to find the original treadmill negatives and sound tapes, since the silent black and white version was just a workprint dupe (although I don't know why it was silent--maybe they never recorded sound for it and planned to ADR the few lines). In fact, I really would like to see that workprint released in its entirety, like on Blade Runner. As much as I hate the idea of plunking down $120 for the SE yet AGAIN, I wouldn't even give it a second thought if it had the whole workprint. Deleted scenes, no, those will just go on Youtube. Stuff like a whole workprint is how they have to win over OOT'ers.
