In what I've read of the WONs from the era, Vince's national expansion was THE big story, so the smaller groups were just covered in a blurb. Blurbs eventually got to something like "not much news out of ___ this week" until finally their section was no more. I don't think there was any real opinion thrown onto it because so much attention was paid to the WWF's takeover. The opinion on that seemed rather negative IIRC with many dismissing "cartoon wrestling" as a fad. I think a lot of them expected something (maybe Hogan falling out with Vince?) to derail that train before long. I remember reading a line like "Vince McMahon and the WWF are here to stay" that came long after I thought Meltzer should've known that. It might have even been in reference to WrestleMania III.
In contrast to the more modern WCW/ECW/possibly TNA soon collapses, I don't think most of the territories had that sort of spectacular failure that merited deep consideration like that. I don't imagine a lot of people that attended these promotions' final cards actually knew it was the final card. At least not at the time or for a long while after.
Wade Keller of the Torch posted some episodes of a weekly radio show he did around the early '90s that chronicled immediate post-mortem AWA pretty well. They tried in a lot of cases to promote local cards, but most callers only wanted to discuss the identities of that week's WWF and WCW TV debuts or "whatever happened to ___?" Some weeks there'd be an update on a Verne Gagne-helmed project that I don't think ever came to fruition, with the tone of it evolving from "hey, maybe this thing can compete" to eventually the occasional wry mention.
