It seems Vessel of Hatred will not be going the Diablo 3 route, and is skipping a physical Collector’s Edition.
As shared in an X reply by franchise General Manager Rod Fergusson, there are no plans for the expansion to get the luxury treatment like the base game did.
This is a little surprising, as Blizzard have actually been ramping up the special editions of their games recently. Whatever the reason, this will leave some collectors unhappy. Whether this is a specific decision related to only Vessel of Hatred or if all future Diablo 4 expansions will also skip a physical Collector’s Edition is unclear.
