According to Tabata, it wasnt long ago they came to know the PS4 Pro. As a result they really havent had time to take full advantage of the new hardware. At the moment they havent been able to show something satisfying.
Tabata says they still have time to work on it and can assure fans a Pro patch will be available when Final Fantasy XV launches on November 29. He says the game will be optimized for the console and will be even more beautiful.
