A few days ago, during a livestream from Gamescom, Final Fantasy XV Director Hajime Tabata teased what appeared to be a possible Nintendo Switch version of the game.
They also made tests on Unity and Unreal Engine 4, and they noticed that those ran well on Switch.
The development team is testing out what kind of specs the Switch can provide.
For the time being they stopped there, but they’re still looking into the Switch, to see what they can do on it.
