Sony always prevented cross-platform play between the PlayStation 4 and other consoles, but things recently escalated with the whole Fortnite fiasco, which prevented Epic Games accounts that have been used on the PlayStation 4 version of the game from being used with the recent Nintendo Switch release. Following so much silence on the matter, the company finally spoke on it today.

During the Gamelab conference today, as reported by Eurogamer, Sony Interactive Entertainment CEO Shawn Lyden finally addressed the matter, saying that they are listening to the feedback and are looking at a lot of possibilities to make cross-platform play work.
