Diablo IV Season 10, Infernal Chaos, launches at the end of September, bringing Chaos Perks, Chaos Armor, and a new Infernal Horde system. But beyond this season’s content, players are looking further ahead already! A mysterious new IP collaboration, the delayed expansion now set for 2026, and what the next phase for the game is!
As a reminder, this was the Roadmap:

Season 10 – Chaos Powers and What’s Left
From the old Roadmap, we know that Season 10 will close out the “Age of Hatred” roadmap with several big features:
- Chaos Perks – new abilities.
- Chaos Armor – new item type that turns Uniques into even more powerful items, opening more build possibilities.
- Infernal Horde Updates – more fun and rewarding Hordes.
- The second IP collaboration – still a complete mystery.
The core gameplay changes are already generating excitement, but it is the unknown collab that has the community talking right now.
The Next IP Collaboration: More Than Just Cosmetics?
Earlier this year, Diablo IV’s first crossover brought Berserk into Sanctuary. The collab made sense theme-wise, but the execution left many players underwhelmed. Instead of a meaningful event, we got a basic reliquary with no quest or anything, and premium cosmetics that cost as much as €30 per item.
With the second collab that should drop before the end of 2025, expectations are high. Will Blizzard take it further this time with new bosses, mechanics, or story tie-ins? Or will it be another cosmetic drop?
For now, it is still a mystery, but one thing is certain! Players want this collab to feel rewarding and worth engaging with, not just another cash shop game.
Why the Expansion Was Delayed to 2026
Thanks to the roadmap, we also know that the next expansion is planned for a 2026 release. The reasoning is clear, especially after all the latest hype from content creators who got an early preview of future content. Blizzard wants, and needs, to polish, scope, and deliver something worthy of keeping players invested long-term. Blizzard appears to be buying time as they are laying the groundwork for larger systemic changes.
This delay also lines up with features that make the most sense alongside an expansion launch, such as:
- Leaderboards and ranking systems
- Major narrative arcs
- New zones and classes
Season 10, the mystery collab, and then the long wait for the expansion could redefine the game.
Diablo IV still has plenty of cards left to play in 2025. But all eyes are really on the bigger picture! Blizzard needs to make the next IP collaboration feel like an event instead of a store page, and the 2026 expansion needs to deliver on the promises we have been waiting for!
