In the past few days, we've learned a lot about Fortnite: Battle Royale's upcoming cross-play support. The PS4 edition will support cross-play with PC and the newly announced mobile edition, while the Xbox One version will also let you play with people on PC and mobile. However, there is no cross-play support between PS4 and Xbox One. There never has been for any game, but all the same, people really want to see it happen. In a somewhat encouraging development, Xbox boss Phil Spencer and developer Epic Games have said they would like to see cross-play added between the two competing home consoles.

This played out over Twitter this weekend. Someone asked Spencer if there would be cross-play, saying they would really like to see the feature added. "Me 2," Spencer said. Later in the thread, Epic jumped in to voice its own support, exclaiming "We 3!"
