If none of these events reveal or dive into what Diablo 4 could be. The day after, there will be a panel examining more of the overall Diablo world, and Blizzard's history with the series. The panel - called Diablo: What's Next - will take place on November 2, and promises to tell players about where the Diablo universe is going next. We already know that at BlizzCon 2018, Blizzard will be hosting a panel dedicated to the future of Diablo - and it'll be taking place immediately after the opening showcase for the big event. So, will Diablo 4 be called Reign of Terror? It seems likely! We're expecting Blizzard to formally unveil something relating to the series in the upcoming weeks over at BlizzCon 2018, and this seems to be laying the foundations for that. There's a new poster, and new shirts featuring the branding.

Over on the Blizzard Gear page, we can see new merch that refers to Diablo: Reign of Terror - an as yet unannounced expansion or new project related to the game. Blizzard has updated its merch page with a slew of new items that seem to confirm a new Diablo project is in the works.
