Takahisa Taura is the same Square Enix lead who worked with the studio on Nier: Automata. This was a strong sign of a continuing relationship between the two companies. While PlatinumGames made a hit with Square Enix with Nier: Automata, the two companies then made a fumble with the poorly received live service game Babylon's Fall. Of course, there would presumably be less friction between the Final Fantasy team and the Kingdom Hearts team. It is worth noting that even if there are overlap between individual developers, there are separate internal Square Enix studios working on both franchises. But mainly, this is a big move for Square Enix, indicating that they really wanted to move away from the turn based combat systems the franchise was known for. Even in a heavily modified form, turn based combat was present even as late as Final Fantasy XV.
