Summary
BlizzCon 2026 is almost here, bringing the Diablo community together in Anaheim and around the world on September 12-13. The event will celebrate 30 years of Diablo while giving players a closer look at the future of Sanctuary.
Blizzard has already confirmed several Diablo panels, including Diablo: Developer Update and Diablo IV: What's Next. The event will also feature Twitch Drops, an exclusive Diablo Twitch badge, and coverage from numerous Diablo creators.
At the same time, plenty of rumors are circulating about what Blizzard could reveal, from a potential Diablo 4 expansion to new endgame systems and class changes. Here is everything to know about Diablo 4 at BlizzCon 2026, including the Season 15 start date, confirmed schedule, rumors, and Twitch Drops. To prepare for the upcoming content, buy Diablo 4 Gold and stock up on resources.
Diablo BlizzCon 2026 Schedule
Blizzard has confirmed several Diablo presentations across the two-day event. Most Diablo broadcast content will be available through the official Diablo channels on YouTube and Twitch.
Saturday, September 12
Opening Ceremonies - 10:15 a.m. PT
The Opening Ceremony will be held on the Main Stage, with Blizzard Entertainment President Johanna Faries joined by leaders from across Blizzard's franchises.
Diablo will take center stage as Blizzard reveals plans for the future of Sanctuary. The ceremony will also be simulcast through Blizzard's official YouTube and Twitch channels.
Diablo: Developer Update - 1:45 p.m. PT
Later on Saturday, the Diablo development team will take the Main Stage for a Developer Update. The presentation will focus on the ideas, development work, and ambition shaping the Diablo franchise.
The Art of Darkness: Behind Diablo 4's Cinematics - 4:15 p.m. PT
This Legends Stage panel will take players behind the scenes of Diablo 4's cinematics, covering visual storytelling, performance, animation, and the creative process behind Sanctuary's darkest moments.
Sunday, September 13
Diablo Immortal Live Artist Drawing - 10:00 a.m. PT
The Diablo Immortal art team will host a live drawing session with a special guest while discussing the process behind creating characters and worlds for Diablo.
Diablo IV: What's Next - 11:00 a.m. PT
This is arguably the most important Diablo 4 presentation of the weekend.
Blizzard says the development team will preview upcoming content, features, and more as part of the franchise's 30th anniversary celebration. For Diablo 4 players, this is the panel to watch for information about the game's next stage.
Voices of Blizzard - 3:15 p.m. PT
The weekend will close with Blizzard voice talent sharing stories and revisiting memorable performances from the company's games.
Diablo 4 Season 15 Start Date
Diablo 4 Season 15 is expected to launch shortly after BlizzCon 2026. The timing is particularly notable because the Diablo IV: What's Next presentation takes place on September 13, immediately before the new season's expected arrival.
The second source also predicts that Season 15 will be a major part of Blizzard's BlizzCon discussion and that the new season is scheduled to arrive shortly after the event.
However, the provided official preview does not give a specific Season 15 launch date. Players should therefore watch Blizzard's BlizzCon announcements for the final timing and additional seasonal details.
What Could Blizzard Reveal?
The official schedule confirms that Blizzard will discuss the future of Diablo, but it does not reveal every announcement planned for the event. This has led to considerable speculation about what could be shown.
A New Diablo 4 Expansion
One of the biggest predictions is a new Diablo 4 expansion involving Baal, the Lord of Destruction.
The theory is based partly on recent hints and Diablo 4's story direction. The prediction is that Baal could become the next major threat, with Diablo potentially playing a larger role later.
This remains a rumor rather than confirmed information from Blizzard. Still, an expansion announcement would fit the scale of BlizzCon and the franchise's 30th anniversary.
New Endgame Systems and Class Changes
Another possibility is a focus on improving Diablo 4's existing gameplay rather than simply adding a new class.
The speculation includes new endgame systems, class reworks, balance improvements, and broader quality-of-life changes. These would address some of the areas that long-term players have been asking Blizzard to improve.
A new class is also possible, but the second source considers it less important than improving existing classes and adding meaningful endgame content.
Is Diablo 5 Coming?
Despite the excitement surrounding BlizzCon, a Diablo 5 announcement does not appear to be the most realistic expectation.
The reasoning is straightforward: Diablo 4 launched in 2023, and Blizzard is still actively expanding the current game. The more likely scenario is another Diablo 4 expansion and additional seasonal and endgame content.
Diablo 5 could eventually happen, but it should not be treated as an expected BlizzCon 2026 announcement.
Other Diablo Rumors
There are also rumors about a Diablo-related television or streaming project, as well as possible updates to Diablo II: Resurrected.
The second source discusses speculation around additional Diablo II content, including potential story and Act changes. However, none of these details are confirmed in Blizzard's official BlizzCon preview.
For that reason, they should be viewed as possibilities rather than announcements.
Diablo BlizzCon 2026 Twitch Drops
Blizzard has confirmed a special Diablo IV Twitch Drops event alongside BlizzCon 2026.
The event starts on September 12 at 10:00 a.m. PT and ends on September 15 at 9:59 a.m. PT.
Players can earn cosmetics by watching eligible streams in the Diablo IV category on Twitch.
Twitch Drop Rewards
The rewards are unlocked according to total watch time:
2 Hours: Serrated Skean Dagger
4 Hours: Corroded Cleaver Axe
6 Hours: Tintinnabulation Two-Handed Mace
You do not need to own Diablo IV or Lord of Hatred to earn progress toward these Twitch Drops.
You can also switch between eligible Diablo IV channels without losing your progress. However, watching multiple channels simultaneously will not make the rewards unlock faster.
How to Get Diablo 4 Twitch Drops
First, connect your Twitch account to your Battle.net account. Then watch any eligible Diablo IV stream during the event period.
You can earn progress through a PC or Mac web browser or the Twitch app on Android and iOS. Twitch apps on consoles, smart TVs, and other TV platforms do not support Drops.
Once you reach a reward's required watch time, you must claim the reward through Twitch or your Drops Inventory. The rewards are not automatically added simply because you watched enough hours.
BlizzCon 2026 Twitch Badge
In addition to the Diablo IV cosmetics, Blizzard is introducing its first event chat badge specifically for BlizzCon 2026.
The badge celebrates Diablo's 30th anniversary and can be earned by purchasing one subscription to any creator streaming in a Diablo category between September 12 at 10:00 a.m. PT and September 26 at 9:59 a.m. PT.
The eligible categories include Diablo II: Resurrected, Diablo III, Diablo Immortal, and Diablo IV.
Diablo Creators to Watch
Diablo creators will also provide coverage directly from the BlizzCon show floor. Blizzard developers are expected to join participating creators for interviews throughout the event.
Diablo IV creators listed by Blizzard include Rhykker, Wudijo, Rob2628, DatModz, Cliptis, Aaron Action RPG, MacrobioBoi, AnnacakeLIVE, and Slaydra.
This gives players watching from home another way to follow announcements and get additional reactions throughout the weekend.
What to Watch at BlizzCon 2026
BlizzCon 2026 should be an important weekend for Diablo 4 players. Blizzard has already confirmed a full schedule of Diablo programming, with Diablo IV: What's Next standing out as the key presentation for the game's future.
Season 15 is expected to arrive shortly after the event, while rumors point toward a possible new expansion, additional endgame systems, class changes, and other Diablo projects.
Those rumored announcements remain unconfirmed, so the safest expectations should come from Blizzard's official schedule. Regardless of what is revealed, players can also take advantage of the BlizzCon Twitch Drops from September 12-15 and earn three Diablo IV weapon cosmetics by watching eligible streams. To make the most of the event, Diablo 4 Gold can help you prepare your characters and resources.
