With Sony announcing that it’s finally allowing cross-platform play starting with Fortnite, it’s understandable that most gamers are salivating at the thought of having their old — and upcoming — multiplayer games playable with the player base of the PS4, Xbox One, PC, and Nintendo Switch included.

If you’re counting on cross-play for games like Destiny 2, Overwatch, or the upcoming Call of Duty: Black Ops 4, well, you’re out of luck. In a statement given by an Activision spokesperson to IGN (via GamesIndustry), the publisher confirmed that there’s “a lot of work to do” to before this becomes a reality.

We’ve had a great experience with cross-play for Hearthstone on other platforms and have witnessed how compelling it can be for our community. There’s still a lot of work to do on both our side and the platform side to understand whether cross-play might be integrated into our other games, so we’ll be watching the upcoming test and will assess what the potential impact of this feature would be for our players and our games.

Given that the announcement was just made a few days ago, I wouldn’t expect most AAA games to be joining the cross-play party anytime soon. Case in point? Bethesda has confirmed that the upcoming online action RPG Fallout 76 won’t support cross-play.
