Your main problem is taking Rainces at his word. To be fair, there was at least one time in the last few years when he has said "one month", and it was actually one month. Usually, he says "one month" or "it is in beta testing", and then he disappears for several months or longer. I've always had the suspicion he says stuff like this just to make people sign up for his patreon in anticipation of a new update about to drop. I've followed this game for way longer than I'd like to think, so I just ignore his promises and wait until I actually see the update posted before I believe. Rainces makes all kinds of promises that either don't come true, or where the timeline is way, way off. Maybe things are different, given they said they lost their job and need the money. But at the same time I'm not automatically believing anything they say.
And as others have said, Rainces is likely to lose this new Patreon page because they're going about it all wrong. As soon as that happens, there's an excellent chance that Rainces goes silent again for an extended period of time. It's possible they still drop the next update, but I think that unless they can find a way to make decent money out of it, they won't. Making money out of the current BBS requires more complexity and guile than they've shown themselves capable of. It's very hard to do without Patreon if you're in this for the money. But BBS as it stands right now won't fly there, and Rainces just doesn't seem to get that showing any connection between their new page and their old game is not a good idea.
