No platform split was shared this time, unfortunately.

25 million players on PC, PlayStation 4 and Xbox One. We don’t know about the details for specific platforms, but that’s an doubtlessly impressive achievement.
We should remind you that Overwatch celebrates the Year of the Rooster as millions of its players live in Asia. If you haven’t played it already, you definitely should give the game a try.
