Blizzard has been quite mum of what their plans are after "Diablo 3," but it appears that they are not very keen on developing a sequel for Diablo. While it is not yet firmly established that all plans for "Diablo 4" have been scrapped, it appears that the studio is taking it's time to carefully plan their next steps so that fans do not get upset.
GamenGuide previously reported that fans are anticipating Blizzard's big event, Blizzcon, which is set to take place in Anaheim, California on November 4 and 5. Fans are anticipating some huge announcements from the studio in their upcoming projects and a lot of them are expecting that "Diablo 4" might be included amongst those announcements.
Earlier, fans were disappointed when Blizzard did not give out any details at all about the "Diablo" franchise at Gamescom which took place way back in August 2016. Many have thought that the company might have saved bigger news for its own major event since the company had announced on Twitter that they have something huge to reveal very soon.
Fan speculations for "Diablo 4" began to arise when job positions for the Diablo franchise were posted in the Blizzard career site. This, however, does not necessarily mean that a "Diablo 4" is coming but can also mean that Blizzard will be working on another "Diablo 3" expansion soon. The posted positions, including that of game director, were immediately filled in and the newly hired team is said to develop an unannounced Diablo game very soon.
Some rumors, however, do not want to get fans to optimistic as they say that Blizzard is simply hiring a new team to maintain "Diablo 3" or could be developing something entirely new but largely connected to Diablo. If Blizzard does not have its hands full in developing another "Diablo 3" expansion or a "Diablo 4," another possibility arises that the studio could be developing remastered versions of "Diablo" and "Diablo 2." Whatever Blizzard has in store for its fans should be big enough to satisfy them when they bare all in the upcoming Blizzcon.
