Well, yeah. But there's loads of references to dozens of past adventures. It's hard to tell what's just an Easter Egg for the fans and what's a clue for future stories.Yeah, for Mindflayer stuff, I expect there to be a Firestorm Peak inspired storyline at some point, considering the multiple hi ts toward that. But who knows when they might do it, rather than sow more hints.
As the first reference to the Far Realm Gates of Firestorm Peak are going to come up in a few aberration's entries. However, it's mostly a duergar adventure before things get Lovecraftian with gibbering mouthers, mutated humanoids, deep spawn, and some unique beasties. Not a lot of Mind Flayers.
I imagine it might be part of a multi-module mash-up, like Tomb of Annihilation*, where it's combined with a couple other classic ideas into something new.
*ToA being a combination of Isle of Dread, Dwellers of the Forbidden City, and Tomb of Horrors.
