Kotaku's Jason Schreier reported on Twitter part of his interview with Square Enix's Yoshinori Kitase during E3 2019. When asked about how many parts Final Fantasy 7 Remake will be, Yoshinari Kitase answered that they don't know yet themselves.

Square Enix already mentioned multiple times in the past that Final Fantasy 7 Remake will be in multiple parts, each part forming a full game experience. The first part of the Final Fantasy 7 Remake will be covering all the initial events in Midgard from the original game. In the original FF7, this part didn't last more than ten hours even by dragging one's feet, so it's quite intriguing to see what will be added to make this first part in the remake a " full game".

I have to say it's a bit worrying, as I'm wondering when the sequels parts of Final Fantasy 7 Remake will be launching. I'm not sure waiting over a year between each part, which is an optimistic estimate, would feel that great. I'm starting to wonder how many years will it take for us to see Yuffie, Cid, Vincent, and Cait Sith supposing they don't have cameos in the first part.

Final Fantasy 7 Remake is launching on March 3, 2020, exclusively on PS4. The game will be shipping on two Blu-rays. You can take a look at the two Limited Editions.

At E3 2019, Final Fantasy 7 Remake got a brand new trailer and an explanation of its battle system and Materia system, with pre-recorded gameplay showing Cloud and Barett fighting the Scorpion Sentinel.

Update: According to Twinfinite, Square Enix is currently deciding on what to include in the second Final Fantasy 7 Remake game and how much content will it cover. As such, this is what Yoshinori Kitase meant when saying they don't know yet how many parts it will be.

In short, it means that the number of parts will vary depending on how much content is covered in the second part.
