Blizzard used the BlizzCon 2026 Opening Ceremony to outline an unusually broad slate of projects and updates. The presentation covered immediate releases for Warcraft III: Reforged, new characters for Heroes of the Storm and Overwatch, major expansions for established games, and long-range projects including Diablo V and a StarCraft open-world shooter.
What happened at BlizzCon 2026
Heroes of the Storm is receiving Xal'atath, the World of Warcraft character, on September 28, suggesting Blizzard is ready to give the crossover MOBA renewed attention. Overwatch also introduced Doctrine, a vampiric Support hero. Players can try him during a Hero Trial from September 12 to 14, with a full unlock planned for Season 5.
Diablo was one of the ceremony's biggest subjects. Diablo IV's Age of Hatred season will be accompanied by a Switch 2 release on September 15, while Diablo V is targeting spring 2029. The next mainline entry takes place in a Sanctuary without towns or safe havens, a premise Blizzard says will affect how players approach the game. Netflix is also developing an animated Diablo series, although no further details were provided.
The StarCraft universe is returning as an open-world shooter led by former Far Cry lead Dan Hay. A cinematic established a grim tone, with the project currently targeting 2030.
Why it matters for Blizzard's live games
Hearthstone is expanding with Reign of the Black Empire, an Old Gods-themed set built around combining keywords on a single card. Battlegrounds will add Aberrations, the Journal will provide more lore, and a new Tavern Brawl will support 2v2 play. The Monk class, Hearthstone's first new class in some time, is scheduled for March 2027.
World of Warcraft's Worldsoul saga is moving toward a crisis involving Xal'atath and the Worldsoul. Midnight Eclipse will continue that storyline, while The Last Titan is planned for 2027 and is positioned as a major chapter in the saga. Warcraft III: Reforged, meanwhile, receives the Forsaken Kingdom campaign today, focused on the fall of Lordaeron, alongside quality-of-life, graphical, and engine improvements.
The ceremony ended with World of Warcraft Forever, a re-envisioning of the classic MMORPG. It adds zones including Mount Hyjal and the Riverglades, expands original areas, and introduces raids, dungeons, reputations, skills, talents, new race-and-class combinations, and the Skyborne race. Its beta begins September 17, ahead of the November 4 launch.
What to watch next
The immediate schedule is packed, but Blizzard's most consequential announcements are further away. Diablo V has a defined 2029 window, while StarCraft's shooter is still aiming for 2030. Those projects will need sustained updates to maintain interest during a long development cycle.
In the nearer term, World of Warcraft Forever could become the ceremony's most visible player-facing release, especially with its beta arriving before launch. The Last Titan and Midnight Eclipse will also clarify how Blizzard intends to conclude and extend the Worldsoul saga. For competitive and live-service audiences, the key question is whether the renewed attention on Heroes of the Storm, Overwatch, and Hearthstone becomes a continuing content strategy rather than a one-event burst.

Expert View
BlizzCon 2026 presented Blizzard as a studio balancing long-term bets with immediate support for its existing catalog. The strongest signal is the range: classic Warcraft, modern live games, television adaptation, and two major new franchises or sequels all appeared in one ceremony. The risk is equally clear: several of the most ambitious announcements are years away, so the quality and consistency of interim updates will determine whether this momentum lasts.
