Considering they worked with Dontnod Entertainment who made an episodic game, Life Is Strange, they used player feedback through basically a free version of Ground Zeroes through Episode: Duscae for Final Fantasy XV, and that games are getting bigger and bigger and more difficult to manage, I wouldn't be surprised if they split Final Fantasy VII into 5 parts with 3 parts being the main game, an intro, middle/body, and conclusion, and perhaps even a "prologue" through a remake of Crisis Core and an "epilogue" through a playable Advent Children. If they do it right, let's say the main game parts costs 20 USD each and the others are just 15 USD, they could sell it well without angering people.
The issue with games nowadays is that they're bordering 50 GBs per game and I don't think we have 100 GB discs available for consumer use and even then, downloading that is a nightmare which is somewhat alleviated with pre-downloads, but that only happens if you buy pre-order. It's not even so much content at times; it's the quality of content we're reaching where really detailed, taxing physics, and other stuff is taking a toll on how much data is used.
Content-wise, Capcom is already doing this with Street Fighter V where initially, the game only has 16 characters before any other characters are released. Killer Instinct did this as well with seasons. In my opinion, it would have been a better idea if Smash 4 was released with at most, 25 characters. It might have been better for them to add characters per "generation" like initially, the game only has the original fighters followed by the Melee newcomers and so on. Smash 5 might and probably will have to do this if they don't want to kill themselves. There's 50+ characters plus whatever else that you'd have to balance by launch and since Brawl, they had to delay the game.
For FFVII that's a RPG and made by a company known for graphics? That's definitely going to take a toll on the developers to not kill themselves with traditional game development and releases. And they already showed that toll with Final Fantasy XIII where there was enough cut content for an entire game. Imagine if XIII was split up into 3 releases as one game. It might have ended completely different and received completely different.
