As it turns out, those leaks were largely correct.

It’s coming to PC, PS4 and Xbox One, and presumably next-gen consoles, but no date for its release has been revealed.Prior to the game's reveal at BlizzCon 2019, leaks claimed to reveal Diablo 4's playable classes. It’s been confirmed that the new map will be one, giant landmass, where players can encounter each other in the wild, teaming up or even fighting each other. These are not all the classes, but these three are playable at the show.

The Druid is a savage shapeshifter whose updated playstyle empowers them to fluidly transform between werewolf, werebear, and human form to unleash the raw power of nature’s fury on the forces of the Burning Hells.

The Sorceress hearkens back to their Diablo II roots and shapes the elements to obliterate their foes by impaling them upon jagged spikes of ice, electrocuting them with bolts of lightning, or raining flaming meteors from the sky.The Barbarian, known for their unparalleled strength and brutal melee combat, utilizes a new and more powerful system in battle, Arsenal, which arms them with the ability to carry and rapidly switch between four different weapons at a time by assigning them to individual attacks.

Update: Blizzard has just released a PR sheet on three of the classes coming to the game: Perhaps Blizzard will speak about it more over the course of BlizzCon, but for now all we can do is hyper analyze this lengthy trailer for clues. What is not given in the new trailer is a release date or release window for Diablo 4, and I would be stunned if we see it before 2021. I’m unclear who the grey man is who helps summoner, but I wonder if he could be one of her “children,” a Necromancer. It appears that with Diablo down, Lilith is poised to take up his mantle of the seat of evil power in the world after previously being a somewhat minor character.
