Today the Japanese convenience store chain Seven Eleven released the digital download cards for the PS4 version of Final Fantasy XV, and they include the mention that the game requires 45 gigabytes of more of hard disk drive space.
You can check them in the pictures below.
Incidentally, the dispenser still mentions that the game will launch on September 30th at midnight. This seems to be conflict with the latest rumor about a delay, but of course it might have simply been printed before the alleged delay was decided. We’ll still have to wait and see about that.
