Final Fantasy 7 Rebirth is a PS5 exclusive, which probably should not surprise fans. After all, Square Enix already made Final Fantasy VII Remake Intergrade exclusive to Sony's flagship console. It only makes sense for the game's sequel to do the same as well.
It would be easy to chalk up the PS5 exclusivity of the next Final Fantasy 7 installment to the natural life cycle of consoles. Since Sony is expected to phase out the PS4 by 2023 or 2024, Final Fantasy 7 Remake Rebirth should be exclusive to the PS5. But, it appears that Square Enix has a very good reason for doing this. We doubt anyone will complain once they find out why the second part of the Final Fantasy 7 Remake trilogy is a PS5 exclusive.
Here is what Square Enix had to say in a compilation of interviews by Gematsu:
It's exclusive to PlayStation 5 because of the graphical quality, of course, as well as SSD access speed. Since the adventure unfolds in a vast world after the escape from Midgar, loading stress is an extreme bottleneck. We felt we needed the specifications of [the] PlayStation 5 to overcome that and travel the world comfortably."
This doesn't necessarily confirm that FF7 Rebirth will have open-world elements, but it does hint at a more massive adventure lying ahead. Then again, the ending of FF7 Remake guaranteed this would happen. As the party heads out of Midgar, Cloud and his friends will likely explore the rest of Gaia, or at least the rest of the eastern continent in Rebirth. Either way, we are excited to see what Tetsuya Nomura has in store for audiences for the incoming sequel.
The PS5 is a powerful console with a powerful proprietary SSD. Ratchet & Clank: Rift Apart was a rare showcase of the PS5's true capabilities as it let players transport between worlds seamlessly. If Rebirth will utilize the capability of the PS5, we can expect great things from Rebirth.
Having said that, we can't help but wonder how FF7 Rebirth will handle requiring an SSD on the PC. The PC port is still unconfirmed, but FF7 Remake is on Steam and the Epic Games Store. If Rebirth follows suit, Square Enix might ask the digital storefronts to include an SSD in the game's minimum system requirements.
