Psyonix has announced that cross play between Xbox One and PS4 is all ready to go.
All they’re waiting for is the go ahead from Sony. Once Sony approve the feature, it could be up within ‘hours’
“Right now, we’re literally at the point where all we need is the go-ahead on the Sony side and we can, in less than a business day, turn it on and have it up and working no problem. It’d literally take a few hours to propagate throughout the whole world, so really we’re just waiting on the permission to do so.”
It’s still not know whether Sony is going to allow the feature to be switched on.
But currently Xbox One and PS4 users are allowed to play with or against PC players.
Peronsally, I think it would be a bad move for Sony to reject it, especially in a world where we’re trying to bring together the gaming community.
