Diablo 4 has been leaked ahead of an alleged Blizzcon 2019 announcement. 

Spotted by German website GameStar, the title was leaked through a German advertisement for the upcoming game’s official art book.

The advertisement is apparently included in the website’s offline magazine which has been sent out to the magazine’s subscribers. According to a GameStar, the magazine will be out for everyone else on October 23rd.

According to the outlet, the artbook is called The Art of Diablo and is being written by Blizzard’s Robert Brooks.

“Featuring over 500 artworks from Diablo, Diablo II, Diablo III and Diablo IV, this book features many noteworthy artworks created for Blizzard Entertainment’s iconic action RPG, which has given generations of fans everlasting nightmares,” reads the product description.

Knowledge of Diablo 4’s existence in development has been in the wild for a while now. With the title having its development restarted once and resulting in the cancellation of a StarCraft FPS, fans have been anticipating the title ever since the announcement of the Diablo mobile game.

The Diablo 4 art book was also spotted by SpielTimes. While we don’t speak any German, the design of the book is pretty sick.

With Blizzard currently in a crisis PR state following its censorship of pro-Hong Kong rebellion gamer Blitzchung, with the company cancelling PR events, many are wondering what the company has in store for Blizzcon.
