According to an announcement by Blizzard, it seems that the next expansion for World of Warcraft will be announced on the 19th of April. Not much is known right now and all we have is a date to go on.
“On April 19, the World of Warcraft development team will reveal the next expansion. We’re excited to show you what we’ve been working on and where your adventures in Azeroth will go next. Until then, we hope you are enjoying Eternity’s End, the newest content update and final chapter of the Shadowlands saga. The heroes of Azeroth have been called forth to this intriguing new land of Zereth Mortis to thwart the Jailer’s efforts and stop him from rewriting reality as we know it. “
It is unclear how Blizzard plans on moving the story forwards based on the current storyline as the Jailer is seen as one of the biggest bads of the game to date, having been kind of the mastermind behind most of the major events in the Warcraft universe, so it will be interesting to see where the company takes the story next.
