It seems like PS4 and PC owners will have to wait a bit for the beta to hit their platforms.
Fallout 76, the online co-op hared world shooter and RPG from Bethesda that launches later this year, will be getting a public beta to help Bethesda tweak things out ahead of the game’s launch. We already know that for now, the only way to gain access to the game’s beta will be to pre-order it; now we also know that the beta will come to the Xbox One first.
On Bethesda.net, the company has confirmed that Xbox players get to go hands on with the new game first; no reason for why this is happening is given, but it may just be that Bethesda and Microsoft have a marketing deal for this game (Bethesda historically does enter into such deals with Microsoft and Xbox, so that would make sense).
Still, if that’s the extent of the exclusivity, I think in the end, it’s fine- it could be a lot worse. It could be that there was no beta for competing platforms (like Capcom did with Monster Hunter, where Xbox never got a beta), or that game content was outright locked from competing platforms (like Destiny with, again, Xbox).
