Overwatch 2's release date has yet to be shared following the game's announcement at BlizzCon 2019. Blizzard and its team of developers have kept the game and any pertinent information under a tight seal.
A recent Amazon listing may have finally managed to gain some insight in to the securely kept secret of how the game is developing and when fans might be seeing it on the market.
Overwatch 2 Release Date Possibly Teased for Late 2021
An Amazon listing found and shared by Overwatch insider Naeri, displays an Overwatch 2 artbook described as a "sneak peek" in to the game. It also lists the book as not available until October 2021.
The availability date for the book has led to some theories regarding Overwatch 2's release date. Some have seen it as a sign the game will be released around October 2021, which would be a decent timeline for the game being announced in 2019. The less optimistic theories point to the key "sneak peek" part of the description and believe the game won't come out for several months following the release of the artbook.
Of course there is no way to verify any theories regarding the game's release date until official announcement from Blizzard is given. Part of the reason for the lack of information about the game's release is that BlizzCon 2020 was cancelled due to COVID-19. BlizzCon 2021 is still planned at this time and might shed some light on the game.
