After revealing the game at BlizzCon 2019, Blizzard has yet to announce a release date for Overwatch 2. The last we heard was that Overwatch 2, along with Diablo 4, was going to be delayed. Since then, disappointed fans have believed that the Overwatch sequel isn't coming until at least 2023. But, in what is potentially good news from a credible source, Blizzard might start giving players a glimpse of Overwatch 2 soon.
According to Dexerto, several different sources have made similar claims that Blizzard invited Overwatch content creators to attend "secret meetings" and sign non-disclosure agreements. It doesn't take a rocket scientist to deduce that these lowkey powwows are about Overwatch 2. Furthermore, Twitter user FireTheGull, pointed out changes to Overwatch's in-game files that hint at an impending Overwatch 2 demo.
Of course, this remains unconfirmed, so take it with a grain of salt. But, the timing of an Overwatch 2 beta in March would line up with the next season of the Overwatch League.
Last year, Blizzard confirmed that the Overwatch League will start using an early Overwatch 2 build for the 2022 season when it starts in April.
