The prologue will be remade and brought forward into the new iteration of the game at eventually. Of course, we should expect some retcons to allow things to fit correctly. The prologue as it is is only semi-canon and used to outline events that happened during the time between waking up and where we start off in the current version of the story.
How soon work begins on remaking that content has so far been dependant on what Patrons have voted on wanting SLim to work on first and they've prioritised new content, but I think I saw SLim say (in a comment response on Patreon?) that he'll have to just do it at some point without a poll pushing him since new content will always win these polls.
tldr: SLim intends to remake the prologue content but we don't know when yet.
Yea.. Better to just get it done without a poll, since most wouldn't really care about a remake of old stuff.
Tbh the difference between the prologue and main game seems to me that SLim would be able to remove most of it since to me most of it is non-canon and only the first couple days mattered.
1. Never meet with Juliet again after the hospital.
2. Never did anything with Margaret.
3. Linda was never in a grocery store.
4. Never meet the Purple Orchid owner as a hooker and fucked her.
5. Main game starts right after the day of the toilet incident, so we never went on that date with Sister on that Friday.
Hmm.. Probably a few other things that could be removed for an easier remaster of the prologue.
