PlayStation has moved cross-play support out of beta, according to Sony Interactive Entertainment's Jim Ryan, theoretically making the feature available to all developers.
The change was included in a Wired story on PlayStation Now, which received a steep price-cut earlier this week. The article was based on an interview with SIE CEO Jim Ryan, and mentioned that the PS4 can now support cross-play "on any titles that studios provide the functionality for."
The article went live on the same day that PUBG Corp. confirmed cross-play between Xbox, PC and PlayStation 4.
While Wired's information came straight from the top of Sony, progress on cross-play has yet to be commented upon through the publisher's official channels.
This is characteristic of Sony's stance on cross-play to date. Initially reluctant to lower the walls around the PS4's captive audience, it relented in June 2018 following pressure related to Epic Games' Fortnite.
