Fortnite, in my opinion, in partnership with PlayStation is the best gaming experience for users, we truly believe in it. In fact, we have already opened in some games cross-platform support with PC and other platforms, so our solutions are based on best user experience, said Kenichiro Yoshida.
In other words: players Fortnite on the PS4 will remain within its platform. Moreover, after the synchronization the account with Epic Games on PSN account, the player will just have to stay on PS4, as its progress is blocked for other platforms.
