There are rumors that Call of Duty 2021 will have even more significant Warzone integration than Black Ops Cold War. Considering this, it seems Call of Duty fans can expect game reveals happening in the late summer to be the 'new normal' for the franchise.

It's quite possible that Season 5 will kick off the Call of Duty 2021 reveal, but it could also happen a bit later in the season. As it so happens, the Call of Duty: Warzone battle royale is heading into Season 5 of its Black Ops Cold War crossover on August 12. The 2021 Call of Duty game, rumored to be entitled Call of Duty: Vanguard, is expected to be revealed through the Call of Duty: Warzone battle royale.

It seems that Activision is doing something similar with the 2021 Call of Duty game, which is now expected to be revealed at some point later this month.

However, that changed with Call of Duty: Black Ops Cold War, which wasn't announced until late in the summer of 2020 and released a few months later. For well over a decade, Activision established a pattern of announcing the next Call of Duty game by May of every year.
