I have just red the wiki page on the 9.18 incident.
Yes, that's what I was referring to in my last post. Sorry, for not clarifying.
But still, i do hope 2nd Vision can fix the mistakes made in the early days in the future,
They pretty much already did by having those 4 idols (Ritsuko, Ami, Azusa, Iori) to be producible again in One for All and the newest game Platinum Stars.
but completely cutting off SideM from the main world just to please the male dating sim fans audience is not fair for new fans like me that came from SideM.
I think Cinderella Girls is also pretty much cut off from the main series except for cameo appearances and a few song collaboration. (765pro were initially in the old mobage CG game but were taken out real quick). But, yes, Side M will likely be separate.
Side M connections with 765pro is through Jupiter and Ryo (he is Ritsuko's cousin who initially was part of Dearly Stars before moving to Side M).
