Our upcoming Gwent: The Witcher Card Game will launch in closed beta for PC and Xbox One later this year, and Microsoft already confirmed Gwent's cross-play feature not only between Xbox One and PC, but also other consoles if they allow it. We also do have a technical solution in place for PS4 and would love to add Sonys platform to cross-play at the start of open beta. All we need is a green light from Sony."
