This quote fro Temeura seems to indicate we’ll at least see what he was up to between ROTJ and Mando, if we don’t go back even further.
I’m sure we’ll see Boba escaping the Sarlacc pit, which makes me wonder - which version of it are they going to use? The one which is basically a hole or the one with a beak? (Not that anyone on here needs the special edition changes explained to them)
As we’ve seen/heard with the ‘Han shoots first’ scene in Solo, and the original Krayt dragon sound effect being used for The Marshal, writers and directors of new Star Wars projects tend to be more nostalgic for the original editions and remember the controversy that started in 1997. However, to avoid audience confusion, my guess is they’ll use the beaky SE sarlacc. Assuming we see a sarlacc at all, this should be our most clear pointer as to whether Disney/Lucasfilm are treating the special editions are the canon versions, although it won’t be definitive. It’s more likely that creators will use the special editions for reference when casual/younger fans would be confused and the OOT for reference otherwise. Still an interesting question.
