When it comes to cross-platform multiplayer between Xbox One and other consoles, Sony has proven to be a bit of a stick in the mud. For example, when Microsoft announced the "Better Together" update for Minecraft, which lets Minecraft players play together across Windows 10, Xbox One, iOS, Android, and Nintendo Switch, Sony chose to not allow cross-play on PlayStation 4.
Sony's reluctance has also extended to other games, like Rocket League and ARK: Survival Evolved. It turns out, however, that Microsoft is talking with Sony about bringing PlayStation 4 on board for cross-play for Minecraft. In an interview with GameReactor (via OnMSFT), Xbox marketing head Aaron Greenberg confirmed the talks, stating:
We're talking to Sony [about crossplay], we do partner with them on Minecraft and of course we would like to enable them to be part of that; one community, to unite gamers. So we're talking to them and we're hopeful that they'll be supportive of it.
That's far from saying Sony is on board, but the fact that talks are continuing is a good sign. And who knows: allowing cross-play for Minecraft could eventually lead to enabling it for other titles that support it as well. That would only be good for the gaming community as a whole.
