In the new-timeline scenario I'm picturing, FF7R ends near Meteorfall and we get at most a brief epilogue of events that occur after.They'd have to sit back down and create a new post FFVII story when AC is still there and they'd have to rethink how to rewrite a story that's different from it. They're not doing that lol.
There will be no Geostigma because Sephiroth and Jenova will have met an ultimate end this time around. Deepground will not attack the world because they will already have been annihilated via a new series of events within FF7R. We may even see Shelke reuniting with Shalua in this new pre-Meteorfall scenario. Vincent Valentine will already have had his walking-out-of-cave moment ("You were the reason I survived") with Lucrecia but within FF7R. Lucrecia's fate will also preferably have seen proper closure within FF7R, probably through death but possibly something else. Tifa and the rest will still build Seventh Heaven in Edge and they may still end up adopting Denzel.
From recent interview posted on The Gamer:
When I read these statements I see a ton of ambiguity. Some people will read the above and see this as a definitive statement that FF7R will loop back around to the familiar post-OG continuity. Others will read it and see it as definitely opening the door for a new timeline, with Compilation plots and characters being moved to WITHIN (coming together with, as it were) the FF7R pre-Meteorfall story. Others will read it differently still and not be sure what to believe.Before the release of Episode Intermission, it was unclear if the likes of Advent Children, Dirge of Cerberus, and the range of other Final Fantasy 7 material was considered canonical in the remake’s universe. Toriyama-san confirmed that this is definitely the case, describing the remake project as a “coming together” of sorts for over 20 years of adventures. “I want to make it so fans who know the original game and the different Final Fantasy 7 universe titles can look forward to seeing how they all relate and join up with each other, while at the same time communicating how deep and amazing the world and characters of Final Fantasy 7 are to newcomers who will not have seen any of them,” Toriyama-san explains. “Remake is based on the original, but is being made after all of those additions to the universe, so we want to take advantage of that and are planning it out as a kind of ‘coming together’ of all the works set in the Final Fantasy 7 universe to date.”
I hold my stance that the future is largely open-ended here.
