They couldn't, the cutscenes are video files instead of pre-rendered, there's nothing they could do short of rebuilding them from the ground up.

It was a tech demo sure, a way to show of the technology behind the game, but in essence it's his own thing, not a preview for KH3 as a whole. A demo is a small part of a full game for people to get a feeling of the full product, 0.2 is not a part of KH3.

Only that it isn't, not even the gameplay is the same, 0.2 was just something Nomura wanted to do for a long time now, and since the oportunity to do it has passed he used this chance to bring forward what little he had in mind. It's just a little something for the eager fans wanting for the next chapter.

Your logic doesn't make any sense because 0.2 isn't a demo for KH.

No, they couldn't clean them up, read what we told you, those are not rendered in real time like every other cutscenes in every other game, they're simple video files, only way to clean them would be to create them from scratch again, that would cost them time and money, and they wasted enough of both with the other problems with the first collection, like the fact that they had to rebuild the entirity of KH from a PS2 disc because they lost everything from the first game for example,...

Re:CoM cutscenes are not rendered in real time, they're videos, no way to update those, has been like that since the original PS2 release.

Any of the Dynasty Warriors games has a lot more enemies on screen, as well as the Dead Rising series, KH2 doesn't have all 1000 on screen at the same time, they are cleverly hidden on the background and not rendered all at the same time, any of the games I mentioned render a lot more enemies at the same time.
