Asides from the next entry in the Call of Duty series, there is some new information on what we can expect for Warzone when it comes to the Vanguard release.
Activision and Raven Software have been under fire throughout this year, particularly over the last few months, as Warzone has been plagued with cheaters. The game has become borderline unplayable due to the rampant hacking issue but Activision now promises a solution that will hopefully improve the situation.
Warzone is getting a new anti-cheat system

Aside from the reveal of Vanguard, Activision has shared a few details on what can we expect for Warzone in regards to Vanguard.
And while they have been rather laconic, they did reveal a few pieces of information about the "new Warzone experience" which is slated to come alongside the Vanguard release.
The rumours about the new map (supposedly to bet set in the Pacific theatre of World War 2) are true, and Warzone will get a brand new map in November.
But probably the biggest new feature at this moment is the announcement of a new PC anti-cheat system, something players have been clamouring for since the release of the game, as the current system is simply not doing anything to prevent cheaters from ruining the experience for everyone.
The new anti-cheat has been first reported by Tom Henderson, a well-known Call of Duty insider, and now it is officially announced that Warzone (and other Call of Duty games) are getting the new system against hackers.

Hundreds of thousands of players have been banned this year, but for a free-to-play game, that means nothing, as JGOD explains, because they will simply make a new free account and return the next day.
The hopelessness of the situation is currently best illustrated by the fact that even the biggest Warzone streamers, like NICKMERCS and TimTheTatman, have stopped playing Warzone completely and are now exclusively streaming Apex Legends, though, they did participate in the Battle for Verdansk event.
Call of Duty: Vanguard is slated for release on 5th November 2021, and that's the date when we should expect the new anti-cheat system to come into effect. For many Warzone players, the next two and a half months might be a period when they decide to take a break and wait for the anti-cheat to come.
