Microsoft recently sent out an email to promote Game Pass. There's nothing notable about this. However, the email that was sent out had the subject: "Play Call of Duty, Diablo IV, World of Warcraft, and more of Activision's biggest hits with Game Pass!".
There was also a promotion for World of Warcraft’s Plunderstorm battle royale mode, which recently returned. There was also a console availability graphic next to that image. Once people started noticing what was notable about that particular email, Microsoft had to address it, saying they made a mistake.
Microsoft responded via the Xbox Game Pass X account, in a reply to someone who posted the email and pointed out both the seeming presence WoW on Game Pass and the console graphic:
“this was a mistake on our end ?? sorry for the confusion! Blizzard's World of Warcraft was accidentally included in a game pass email even though it's not available with the service - a correction email will be sent to those who got the original email soon”
To be fair, since Microsoft acquired Activision Blizzard in late 2023, people have been asking for WoW on Game Pass, So seeing this probably got some people excited. Microsoft denying this is seemingly in response to a mistake, but some are still wondering if the denial just means to buy time before there's some kind of official announcement.
With World of Warcraft being subscription-based and with paid expansions, that could be a very difficult ask. Getting a console release could be feasible, but for now, there are no official plans to make what slipped out in these recent promos a reality.
