Practically speaking the odds of finding something that fits all those boxes is basically zero, or getting infinitely closer to zero, or some other tight probability.
And, yeah, SSSS is probably going to be the glue that keeps us together. In another universe where Minna did not make the same decision, though, I feel like a lot of us might've continued following her work even if it was sssomewhat different? Didn't tick off all those boxes? E.g. while aRTD had a pretty different audience, a pretty significant portion of
this forum the audience was willing to jump into SSSS when it came. And these stories
are pretty different, so being open to non-SSSS works that update consistently is probably a good way to go through with this.
OH consistent updates, I forgot to add that. That's also VERY important, from what I see. Because of SSSS's (???) relatively rapid update schedule, people could pretty much come home from their day jobs, sit down, and enjoy a page and all the discussion that came with it. That's a big part of why this community managed to form, and a big part of what we need to consider moving forward. While it could be achieved by following multiple comics, it just won't quite be the
same As for her next work, it's waaay too soon to speculate on its themes, update schedule, tone, pacing, quality, all the stuff. And hey, maybe it'll be a well-paced, well-written story just with a different inspiration. All I personally know is that I won't be into it, based on what Minna's written. And I think most others also know their general stance/feeling about it. But if it isn't, uh, [vague gestures], then I wouldn't have any problems with keeping up with it on a surface level.
