As a general rule of thumb, the sooner a developer allows for the review embargo of their game, the more confident they are in its state and quality at launch. So, when gamers caught wind of when the review embargo if Diablo 4 will end, you'd best bet that a wave of excitement followed.
Although Blizzard Entertainment hasn't confirmed this yet, it's believed that the review embargo of Diablo 4 will lift on May 26 - more than a week before Diablo 4 comes out on June 6.
Twitch streamer, DatModz, was one of the first to break the news. Shortly after, Paul Tassi from Forbes and Jez Corden from Windows Central, both hinted at the said date.
Earlier this month, Blizzardexpressed its confidence in the state of Diablo 4 when it comes out. It appears that the multiple open beta periods for Diablo 4 gave Blizzard multiple opportunities to receive a ton of feedback from its fanbase. Because of this, Diablo 4 is coming out in a flawless state, much to the delight of the thousands of Diablo fans from around the world.
