A brand new Final Fantasy title called Final Fantasy Origin is apparently expected to be revealed at E3 and is being developed exclusively for PS5 by Team Ninja.
the rumored game will be an action RPG similar to Nioh and Dark Souls and could possibly take place in the same universe as the first Final Fantasy game.
The rumored title will also apparently be a PlayStation 5 exclusive, with a PC release "further down the road". Allegedly the game is possibly far enough along that it could also have an alpha demo this summer which is said to be entitled 'Stranger in Paradise.
As of writing, nothing has been confirmed by Square Enix or Team Ninja but E3 is mere weeks away so we'll find out shortly if it's true.
You could always just play Final Fantasy VII Remake Intergrade instead which is due to release on PlayStation 5 on June 10.
