I think a release date of late 2020 is reasonable enough.

Hold there, the game is going to be episodic??? What they are going to do ? Make each disc a stand-alone game???

Come on! I wanna play this already

Think of the FFXIII Trilogy, a set of three games all are connected. FFVII Remake might be a Tetralogy, or Pentalogy.

I think they will it release next year, that's the reason they make more parts, to be faster

FF7 is beeing worked on Unreal 4. They themselves said this.

Working with the mess that is the FFXV engine would make development take longer, not less. It's like you forget that game has been in development for 10 years.

I am hoping they are reconsidering the episodic release and are aiming for a 2018 release for the whole game. Assuming KH3 will be tgeir big title in 2017.

Ah, now I understand. They are going to do an approach like Xenosaga series. It can work well, let's just hope that this time the project continues til the end. SquareSoft released Xenogears with this in mind and didn't turn well also. 

I think they will start releasing it at 2018 and finish by the end of 2019. 

hopefully they just release it quite late but drop the epesodic crap, I would assume earliest somewhere 2017 and latest 2019.

FF15 was using one of their in-house engines. FF7 is using unreal.

They obviously decided writing their own wasn't ultimately worth the effort.
