EA and DICE are seemingly teasing a reveal for Battlefield 6 coming next month according to the game's official Twitter account.
In an extremely brief teaser, they tweeted "Words that rhyme with Soon: June. Boom." My guess would be that the game will show up at E3 2021 and i think it'll be available on Xbox Game Pass. Notable the EA Play addition on Game Pass Ultimate shows on the app to claim by 02/06/2021 which could mean when EA Play leaves the service but that's speculation. Hopefully, I'm wrong on that one but it wouldn't surprise me if EA Play was removed from Game Pass Ultimate and then Ubisoft Plus is added.
