Ah, so the RNA is the loophole here.
And that's the rub, right there.
I expect the OG's plot to exist and be followed, as it did here in the Remake.
However, the writers will express those plot events and scenarios in a myriad of ways. Some of that OG DNA will be decoded and expressed as seen in the original, other events or scenarios may get mutated.
I think it's reasonable to expect to maybe see the Whispers pop up again in the Temple of the Ancients. Especially since in the OG that pool of "knowledge" is what allowed the party to see into the past to witness Sephiroth attacking Tseng, which could fit with the Whispers' timey-wimey stuff.
That'd be fine, I just wouldn't want their role as time-janitors to be repeated.
I mean it is but y'all are in stage 1 denial and willfully choose to ignore it.
If your takeaway from that ending is that we killed fate itself just so everything stays the same with a few sensible adjustments and additions to the story rather than some major differences and controversial changes then I don't know what to tell ya
It's entirely possible that the whole exercise is a means of subverting expectations, only so that when moments that are well known and predictable within the OG arrive, they are able to inflict maximum impact on the audience by adhering to them.
Nomura can be very crafty and is a master at purposeful misdirection. Kingdom Hearts thrives off that shit. The secret ending "Birth By Sleep" spawned a year of people theorizing Roxas was never a nobody, or he would somehow escape Sora's heart and live a life to become a Keyblade Knight, and other ideas because
Nomura created a character with the exact same face as another character, in an
entirely different game. It was literally the "Zack is alive!!" shit before today. Ventus having Roxas face was a purposeful design decision to throw the audience for a loop, and it ended with the answer being "same face, different boy."
That's absurd yet that happened.
Yeah, there will be changes but I believe that this is a purposeful meta-misdirection meant to make us expect the unexpected, while the expected take us totally by surprise.
