EDIT: Hal beat me to it. Let’s use his list, for obvious reasons.
Here’s everything I could think of that’s still in development/discussion for V2. Jump in if I’ve missed anything, and I’ll edit it into this comment:
- Pasana Puppet Show (In development)
- Potentially recoloring Ahch-To to go from nighttime to sunrise? (Discussion – I don’t think we decided one way or the other. I personally like the idea though. Plus, if the sky becomes purple at sunrise, it would symbolize Leia’s new lightsaber color.)
- Finishing lightsaber crackle effects (In development – God bless the heroes working on this one)
- Lightsabers fizzling out near the end of the Death Star battle, and after Palpatine’s defeat (In development, I think? I remember seeing a test clip, possibly done by MR?)
- Maybe incorporating the Kylo on the Falcon deleted scene, if we can figure out a way to add the red cracks in the mask.
Things that have been finalized after a lot of discussion the last few dozen pages, and that we don’t need to bring up anymore:
- Palpatine’s plan and the Snoke connection (Palpatine has been “Every voice” in Kylo’s head. Palpatine hasn’t “always” wanted Rey alive since birth; but he decides to use her as a vessel after Ben reforms.)
- Poe used to be a spice runner
- Rey and Kylo have “become” a Dyad - pending updates (basically implying that their connection has grown in strength since the last movie, rather than them being some arbitrary “Dyad” entity from birth)
- And whatever else has already been incorporated into V2.
