It leaked last week, but now it's official. Call of Duty: Vanguard is the 2021 Call of Duty game, complete with World War 2 theme. And as also leaked, the Call of Duty: Vanguard reveal will take place later this week on Thursday, August 19 inside the Call of Duty: Warzone battle royale. Activision has released the first full length Call of Duty: Vanguard teaser trailer to mark the occasion, while also providing details on when exactly fans can expect the Warzone event to go live.

The Call of Duty: Vanguard reveal will take place at 10:30am PT on August 19 inside Warzone. Activision is hyping the reveal as the Battle of Verdansk, promising that players will get to see the Vanguard reveal live in-game. Prior to the Call of Duty: Vanguard reveal, from 9:30am PT to 10:29am PT on August 19, Call of Duty: Warzone players will be able to participate in a limited-time event with Double XP, Double Weapon XP, and Double Battle Pass XP.

Activision has promised that "more information" will follow, so it remains to be seen exactly how this Call of Duty: Vanguard reveal will play out. There is speculation that the Call of Duty: Warzone Red Doors may be involved, but it's also possible that the reveal will simply consist of a trailer that players have to view in Warzone. Whatever the case may be, Call of Duty fans will find out later this week when the reveal finally takes place.

As fans may recall, Activision did something similar with the Call of Duty: Black Ops Cold War reveal last year, confirming the game's existence through a Warzone event. It's possible that the Call of Duty: Black Ops Cold War reveal in Warzone is a good indication of what fans can expect from the Vanguard reveal on August 19, but it could also be handled completely different. Until August 19 rolls around, or until Activision decides to share more information, all fans can do is speculate.

In the meantime, those who accurately leaked the Call of Duty: Vanguard release date, its World War 2 theme, and other details have made some other interesting claims about the game. If they are to be believed, Call of Duty: Vanguard will have a massive multiplayer player count, plus it will have some serious integration with the Call of Duty: Warzone battle royale.

Rumor has it that Call of Duty: Vanguard will usher in a brand new Warzone map, and maybe that will be part of the reveal on August 19. There's still a lot of questions when it comes to the Call of Duty: Vanguard reveal, but fans will get their answers in due time.

Call of Duty: Vanguard is in development.
