I wouldn't be surprised if you're right about that.
In fact, I can see them somewhat repeating the FFXV(when it was still VSXIII) being ported up from PS3 to PS4 all over again, only this time with FFVII Remake being ported up from PS4 to PS5, because, number one, we hardly heard anything more about the game this year, so I doubt we'll even get a release date even next year, number two, it'll be in three or four part full game parts and it is a massive project, and number three, Nomura's doing finishing touches with KH3 which is coming out next year(assuming that it's not delayed to 2019).
That'd be a first. Their development for mainline FF games has been shit for years now. I mean sure, I hope they finally fix their shit and get that shit together because they know how to make good games, but really, XV was disappointing and a crappy development cycle thing.
Though it doesn't contain anything new, Yoshinori Kitase recently addressed the FFVII Remake in a Q&A video over at EDAMAME Arcade Channel. Many thanks to Radigar for sharing this!

E: How do you feel about the impact FINAL FANTASY has had on the gaming community?
K: After 30 years, it [is] great to see people who were once players now in the industry making the games
As we work on the FINAL FANTASY VII Remake, the staff grew up playing the [original] game…
They have a passion to make the best possible game
At the time I didn’t realise the impact the games had but now seeing fans become creators I understand
E: We are looking forward to the Remake
K: With the fans of the original making the Remake, the next generation of players can enjoy it…
Who in turn will make future games, it’s a great cycle I’m happy to see
We are currently working hard on the FINAL FANTASY VII Remake…
The major difference between the production of the original and the Remake is our ability to communicate with fans
E: Does that mean fans comments might influence the end game?
K: This time we can hear the fans voice while we make the game
E: So if I send in my ideas daily they might get used?
K: Maybe… we do read as many as we can so I feel this is a title we are all working on
The idea of Aerith and Sephiroth being at one point considered to be brother and sister is from the Early Material Files in Page 519 of the FFVII Ultimania Omega. Them being siblings is mentioned as an idea that was "thrown around", so Kitase might not have been around during that specific plot discussion, he may think the idea was tossed around so briefly it doesn't count or he simply does not remember it.
Q: Was FFVII an incomplete game?
K: That’s not the case at all
The first game is everything we wanted it to be
It is the finished complete product
Although it is true we were pushing the deadline towards the end of production
We had members from the Chrono Trigger and SaGa team helping us get it finished
FINAL FANTASY VII is definitely a team effort and thanks to everyones hard work a complete game
Asked his goal for 2018, he explained that about the remake he’d like to work on “comfort,” also playing on words by mentioning that on a personal level hopes to take it easy (using the same word, “raku” which means “ease” or “comfort” if possible.
