I haven’t had time to go through every comment yet, but here are a few things that WON’T be happening in ROTJ:R -

Extra Boba Fett / Boba Surviving - Boba is going to die ( someone already guessed the one way i’m planning on killing him 😉 )

Revised Crawl - the crawl will be staying the same.

Moving the Dagobah scenes to the beginning of the movie - Where does Luke suddenly disappear to during the briefing? And why does Luke only react strangely towards Leia, that she senses, when he reappears at the briefing and not at all before that? It just doesn’t work moving it to the beginning. You lose, not only Luke’s first appearance, which works perfectly, but other moments that have to be cut to accommodate this.

Lightsaber building scene - see above comment for one reason why. Other reason is that the footage is terrible and the Vader lines are awful ( hacked & pieced together dialogue from the films and not the original recording)

Jerjerrod deleted scenes - No amount of restoration/ work done to that footage can ever make it usable to place alongside HD footage.
