The thing that makes it plausible in my mind is they already kinda did the slow trickle of TFA deleted scenes (the physical release had a handful, the digital release had all of those plus one, and then the 3D rerelease had a couple extra ones). Plus the trilogy finally being over may make them less protective of revealing the might have beens (and, in retrospect with TROS, they were probably smart to do so).
True, and some new special features would be good to convince people to buy the complete collection.
I have a feeling a lot of TFA edits are gonna have a bit of a continuity issue on their hands, as I’m sure they’re going to use the Leia “I don’t care” scene in TROS.
That’s possible, but if they use it I bet they will change it quite a lot. The dialogue and context could be changed (Korr Sella died in TFA so Leia would be talking to someone else), and the setting and Leia’s hair and clothes will probably be different. We’ll see.
