Every port* (PS4 > Xbox > PC) of the games, the team made improvements but never implemented them backwards. It would be nice for a PS5 / XboxSX version of the game to match the parity of PC, with increased draw distance, AF, improved ally animations etc. I don't know if they'd put unlocked frame rate on the game but a solid 60fps and actually hitting 4K would be nice.
I think they even improved 0.2 when it was ported as well. I especially wish THAT had its changes patched in!
The thing that would suck would be not having mods. The mods people have made for KH3 have been an absolute joy and not being able to put them into the game on consoles sucks. I really enjoyed the mod that gave you complete control over Riku for the entire game, including overhauled gameplay for him, as well as the Coliseum mod. Plus the pride flag over the PotC Keyblade was lovely. And who could forget Among Us Donald.
I'd love an offline UX / DR game (A Reverse / Rebirth scenario, if you will), and I've spoken about how nice it would be for the D23 show (may it rest in peace, if it ever lived at all???) to be used to also bank assets for older worlds. Same would happen with this but I'd want Unreal Engine for it. Unfortunately I just don't know who'd be left to tackle it since SE doesn't have the resources to make Verum Rex at the same time as KH4. And I'm not sure if they'd want to outsource development entirely.
*Before I get quoted on this with "well actually not
every port," I deliberately left Switch out since it isn't a proper port, just running the game off a PC server in some remote facility.
ANYWAYS
Disney having a special talk is nice. I don't expect anything to really come from this, other than some lovely stories shared by whoever the guests are. I do hope celebrations ramp up for the NA 20th Anniversary. An introspective from the cast would be nice, I don't think they've done any videos for KH since the infamous KH2 videos. I need a David Gallagher sequel, stat.
