Major announcements related to certain of Blizzard's most famous franchises like World of Warcraft typically happen at BlizzCon which usually happens in WOW WOTLK Classic Gold November. The COVID-19 virus has caused a disruption to the system. Blizzard transitioned towards an online BlizzCon event for February 2021. The company also planned an identical online event for February 2022. BlizzCon 2022 was later abandoned due to the ongoing fallout from a number of cases of discrimination and sexual harassment and investigations into Activision Blizzard.
Blizzard said at the time of the event's cancelation that the organization was taking time to "reimagine" what BlizzCon could look like in the future, and the news regarding future events for various Blizzard franchises would be released via official franchise channels, with the BlizzCon team supporting those efforts.
What this all means is that it could mean news on what World of Warcraft 's next expansion will be, updates about the state of World of Warcraft , and how World of Warcraft is shaping up (just to buy WOTLK Gold mention a few) are no longer attached to major fan events but can be made public whenever the teams working on the project are prepared. The news that Blizzard has tweeted that it was working on a new survival game IP is proof from the reality that these kinds of announcements can be made at any time.
