So, what more development could be done with the characters in the future?

[Velvet Scarlatina 607]

If Kingdom Hearts 3 is truly going to tie up everything from previous games, then that would most likely include all regrets and problems all of the main characters have. What will be left to dive into in the next saga?

[Caity 3,946]

New issues will be created to divulge.

E.g., Sora and Kairi develop a romantic relationship, we'll see the problems and battles with that

[Cucco 1,907]

I want to see lea show emotion like in the 358/2 cutscene xion and axel face off

[Rob 5,571]

I'd like to see Sora conflicted because of his love for Kairi and Aqua, and then he chooses Aqua.
