This does not imply that this will happen six months after the PS5's release.
Square Enix has admitted that Final Fantasy XVI will be released on PC, but does not know when it will be released. The PlayStation 5 version is a semi-annual exclusive, but it will certainly not be released six months after its release on the console.
Producer Naoki Yoshida expresses that he and his family would like to release Final Fantasy XVI on PC, but she hasn't revealed anything definitive yet.
Yoshida advised fans in the past to purchase a PlayStation 5 as a guarantee of a free download of Final Fantasy XVI. It is assumed that the Xbox Series version of the game will never be released.
This is an interesting story.
