No official announcement has been made, but a new Diablo project appears to be in the works
A recently posted job listing for a dungeon artist at Blizzard has confirmed a new Diablo project is currently being worked on at the studio.
Whether that new project is for a proper Diablo IV or a new type of game from the franchise remains to be seen, as few details are provided as part of the job listing.
Blizzard, however, does hint it won’t lose what makes Diablo so popular as they are looking for people who are “passionate about working on the dark gothic world of Diablo, making great games, killing millions of monsters and getting loot!”
