Diablo Sale Reasons

Yes. If you mean the 75% discount on Diablo IV on Steam, the timing is almost certainly deliberate.

The biggest reason is BlizzCon 2026 is this weekend, September 12 to 13. Blizzard has specifically said Diablo will be a major part of the event, with announcements during the opening ceremony, a Diablo Developer Update, and a “Diablo IV: What’s Next” presentation on Sunday.

There’s also a very obvious customer-acquisition strategy behind the pricing:

• Diablo IV base game: $49.99 → $12.49, 75% off

• Lord of Hatred, the newest expansion released in April 2026: $39.99 → $29.99, only 25% off

• The complete Age of Hatred Collection, containing Diablo IV + Vessel of Hatred + Lord of Hatred, remains $69.99. [Image omitted from import]Steam Store+1

So Blizzard can practically give away the older base game because the real commercial opportunity is getting someone into the Diablo ecosystem and eventually selling them expansions, cosmetics, seasonal content, and bundles.

There is another important factor: 2026 is Diablo's 30th anniversary. Blizzard is using BlizzCon to celebrate the anniversary while talking about the future of the franchise. [Image omitted from import]Blizzard News

And interestingly, Steam calls it a “Weekend Deal,” but the current offer actually runs until September 24, so you don't have to buy it this weekend. [Image omitted from import]Steam Store

So I would read the 75% price as:

BlizzCon hype + Diablo 30th anniversary + aggressively growing the Diablo IV player base + upselling Lord of Hatred.

At $12.49, though, if you've ever wanted to try Diablo IV, this is a very low-risk entry price. It isn't necessarily a sign that the game is dying. The fact that Blizzard is discounting the base game much harder than the newest expansion actually makes this look much more like a funnel strategy than a clearance sale.

Also, I'd watch tomorrow's BlizzCon announcements before buying the expansions. Blizzard explicitly says it's revealing “extensive plans” for Diablo's future, so something announced September 12 or 13 could affect which edition makes the most sense to buy. [Image omitted from import]Blizzard News
