This is expected to be the same case for the recently announced Diablo 3 for the Nintendo Switch. However it seems that Blizzard is interested in exploring the idea of potential cross-platform play. In an interview with Eurogamer, Blizzard’s Pete Stilwell confirmed that Diablo 3 on the Switch will not have cross-platform support, but also stated that they are interested in pursuing that idea.
According to Stilwell, “It’s not available at this time. I wouldn’t ever take anything off the table, it’s something we’re exploring, that we’re interested in. But it is not currently a feature.” In the past cross-platform amongst consoles was rare, but in recent years we’ve started to see more companies open up to the idea.
So far quite a few major titles have received cross-platform support, such as Minecraft, Rocket League, and Fortnite, just to name a few. Whether or not Blizzard and Nintendo will ultimately bring cross-platform to Diablo 3 on the Switch remains to be seen, but hopefully they will.
