@Starling: The fact that those changes in tone from the OG exist doesn't actually give ANY evidence that they'd undo them though. If anything it's just as likely that we'd see hints of those different tones already present in the Remake that makes them feel like they fit better or more naturally into the most recent canon version of the Original Game's remade content.
While Genesis' commentary isn't necessary for Cloud's narrative perspective in the Reactor scene (and is intentionally obscured like Force said), what makes you think that we won't see a Dumbapple left on the stairs?
The single thing we know for certain about the Remake is that it is being made into multi-part game to encompass everything they want to be able to include as completely as possible. That doesn't sound like a team that's interested in cutting out the expanded content they spent the last 10 years making in the Compilation. It sounds like the exact opposite.
So, I have to say that — based on the limited information that we know so far — it looks like they're probably NOT going to be scrapping major parts of the Compilation, and there's a very real chance that the Compilation WON'T get retconned. Thus far, I don't see a single shred of actual evidence indicating otherwise, (despite the fact that I see it being talked about in bright pink text a lot). If there's something that's been said or suggested about the Compilation content that points to them removing any of it, I'd be interested in hearing it.
tl;dr - currently there's no indication that the Remake is also a reboot, or that they're at all likely to cut out Compilation content rather than adapt the Remake's expanded story to match the Compilation.
@Major Zero: I really hope that Banora and Modeoheim are accessible locations in the Remake for these reasons. (Also, Banora would be a great location to get a Minerva summon Materia or something).

I would say there are several parts in the Famitsu/Dengeki interviews that indicates an intent to distance themselves from the compilation (at the very least, as it is/in the form it is right now).
The choice to not use a sub-title in order to not get the remake confused with a compilation product, shows clearly that this game is its own beast, and the content of the game will stand on its own.
The second part is the answer the give to the direct question about whether it will tie in to the compilation (
Will the story be adjusted to [things like/among other things] fit (literally “be made to match up with”
with the times, or in connection with the compilation?), which goes as follows :
Nomura :
”Apart from delving even deeper into the episodes [of the game], we’re preparing tricks/devices/gimmicks (Author’s note : there was no single word to properly capture the essence of this word) among other things. After all, isn’t it the case that the people who played the original game, the important parts included, knows the story from beginning to end? We’re thinking we want those people as well to be able to get (literally “taste”
surprised [by the story] once again.”
Yoshinori Kitase :
”We don’t want to do a remake that ends with [just] tracing [people’s] nostalgia. We want to make fans of the original excited (literally : “dokidoki”, the sound of a racing heart in Japanese) again. We’re re-adjusting the story putting those [kind of] feelings into it.”
This answer deftly circumvents the very issue of tie-ins, despite that being a central part of the question, and very often in Japanese culture, this is indicative of a negative, or that whatever is going to happen is so different it might as well be a negative.
Also, as I said in another thread, the parts about changing things to surprise people already familiar with FFVII is equally true to the compilation products, meaning that even if they were to borrow from them, they're likely to change/retcon parts of that as well.
The fact of the matter is that a lot of the additions made to FFVII's history in the compilation only make sense in the context of the specific compilation games.
Adding Genesis, or references to Genesis (or Angeal for instance) adds nothing of value to FFVII's plot, unless you're going to add significant parts of Crisis Core itself, but adding significant parts of Crisis Core wouldn't make sense with the flow of the story of the original at all (I mean, who'd be telling Zack's story in the context of the original game? Everybody who could really have told it to any substantial degree are already dead)
FFVII has it's own story - it's own
complete story no-less. It's a story that you can add tons to without even going into the compilation stuff - and while some compilation stuff can work within the context of the original narrative (like the compilation buster sword guard being underneath the original guard, and breaking apart upon the reveal of Cloud's past), many other parts of the compilation are not self-contained in that way.
They only make sense when they're fleshed out within the context of the product they appeared in like CC, or AC.
Adding them to the remake might serve as easter-eggs to fans of the compilation, but they also run the risk of distracting and frustrating new players or people unfamiliar with the less available compilation products (CC was only released for PSP after all).
Finally, people change.
There is a reason that there have been great changes in tone and style throughout the compilation, and retcons as well. This is because teams change, people change, the times change, and the format changes.
The fact that changes have happened continually up until now should alert people to the possibility that things will change once again.
Simply put, if it happened once, why won't it happen again?
Saying, "well they put so much work into the compilation" is a non-starter, because you could just as easily have said that about the original game in reference to future changes made by the compilation, and they did that anyway. Besides, who're they?
Apart from Nojima being writer, the only product I know of in the compilation that actually has the same set-up as this remake more or less, is the team of AC, which happens after FFVII in either case.
In many ways, I'd see AC references as being more likely than CC references, especially seeing as how CC was a relatively minor game by virtue of only being released on PSP.
It's gonna be really interesting to see if they keep compilation things, what compilation things they keep, if they change any compilation things, if they clear up any confusing bits/plot holes in the compilation things, etcetcetc. We all know it so well that we'll be able to spot any easter eggs even if they're tiny, like Dumbapples left on steps or whatever, so even if that's all there is it'll be cool to look out for things.
