No one is pleased with Sony right now and its divisive approach when it comes to cross-play, but so far the company hasn't budged on easing up on the regulations it has in place when it comes to letting folks play together. That's why it's not surprising that, according to Bethesda Game Studios' Todd Howard, there will be no cross-play in the upcoming online title Fallout 76.
During an interview with German publication GameStar, Howard was asked about the eventual possibility of cross-play multiplayer in Bethesda's online-only RPG. He stated that the team would "love" to do that, but that "right now" it's not possible. After a brief pause, he adds that "Sony isn't being as helpful as we want them to be." That's the quote, verbatim, straight from Howard himself.
This isn't a shocking answer, nor should it come as a surprise that Sony isn't exactly being cooperative, especially with the issues surrounding Switch players being unable to access Fortnite with their Epic Games accounts that previously were used on PlayStation 4 and the like. While Sony has made statements that it could be making strides and working on resolving these problems in the future, it certainly hasn't made any advancements toward fixing the issue just yet. We'll just have to wait and see what happens.
