The recently revealed poster and T-shirts are simply product names.
Given Blizzard’s history with “accidental” leaks, many were suitably suspicious when Diablo: Reign of Terror merchandise appeared in the Blizzard Gear Store. Was this referring to a new expansion? Perhaps the suspected HD remaster of Diablo 2? With how closely the poster and T-shirts were revealed to BlizzCon 2018, many assumed it was upcoming new content.
Unfortunately, that doesn’t seem to be the case. A spokesperson for Blizzard spoke to GameSpot about the merchandise and noted, “These are names and copy used for some of the new products available at BlizzCon this year, and not direct references to content at the show.”
Blizzard has, however, confirmed that Diablo will be present at the show. The action RPG will be featured on not one but both days. In fact, the “Diablo: What’s Next” panel will take place right after the main stage keynote, which is essentially the opening of the convention. Compared to the game’s presence last year (read: non-existent), this is a big deal, and we can expect something to be announced.
This is also bolstered by Blizzard itself confirming that new Diablo projects were in development. We already know about Diablo 3: Eternal Collection coming to the Nintendo Switch (sadly without cross-play support planned) on November 2nd. While some of the other projects may take time to release, there’s no doubt that BlizzCon 2018 will belong to the Lord of Destruction. The convention takes place on November 2nd and 3rd, so stay tuned for more coverage.
