This one really bothers me if it's going ahead the way it implies — and says the ACP is completely clueless about story dynamics ... and if they do it properly anyway (unlikely but possible) then it'll be a real feat to not alienate their fans they've managed to carry over.
Pre-silver age stories were one-shots unless the situation just cried out for revisiting, "the situation" generally being the main character and his/her story, but stories need something to resolve — usually a conflict — or they don't really have a point or anything worth continued reading ... a protagonist/antagonist conflict, usually hero/villain, which is why the superheroes died off after WWII — the Nazis were their supervillain and without them they were lost: they had no other interesting conflict until the Silver age made Supervillains more than one-shot amusements ... but Archie could get away with it because their conflicts were slice of life/growing pains/romance based — and when other companies turned to crime and horror for story inspiring conflict, Archie became the primary arbitrator of the CCA and made sure that that didn't happen ... until years into the silver age ...
What the other companies finally realized was that short one-shot self-contained stories didn't hold interest for long — you read them and forgot them ... if they were good you might come back until you hit a bad one or got bored or disgusted with the inconsistency, but no one cared until the stories got consistency and continuity and a "reality" of their own that people would want to come back to and see more of ... Archie never needed that because they were always the old style one-shots — only the characters themselves carried over and always the same ... their superhero line never got anywhere because it never really got out of that rut. Later Archie stories tried to some extent — some early examples like "Time Police" are some of the best remembered, and as the 21st century progressed they did it more and more ... but they had tons of baggage and the multi-issue stories became just longer one-shots ...
To be successfully there has to be a tone, continuity and consistency across everything ... the new Riverdale (comics) seemed to be aiming for that — take the basic characters and have a consistent high school comedy/romance with continuity and it seemed to be working (although reconciling Archie & Jughead has been difficult — easier to call them separate realities) but it's a "real world" drama — the magic is (was) reserved for CHAoS & AWA and maybe Dark Circle ... bringing Sabrina in as a broom-riding witch? it breaks the whole thing ...
I see a few possibilities here — they do as implied and people lose interest, or Jughead spins off in it's own reality as a third Sabrina title (hopefully before it drags down Archie), or, as Jughead is now known for — and the writer did say he would be following Chip's lead — the Sabrina encounter becomes a dream sequence (previous ones have figured prominently on covers before) which might disappoint/alienate some people ...
Sorry for the long ramble ...
