Recently, Blizzard Entertainment and CD Projekt RED revealed details of the Diablo IV collaboration with The Witcher 3. A Geralt-style skin will be added to the ARPG, but there's a catch — it's promised to be given to players who pre-order the story expansion The Witcher 3: Wild Hunt — Songs of the Past via Battle.net or purchase it there after release.
The developers did not announce any plans to add Diablo IV-style content to The Witcher 3: Wild Hunt. During a conversation with the media, lead designer Miles Tost explained that CD Projekt RED strives for content uniformity — so that it is the same on all platforms.
When directly asked by a Polygon journalist whether CD Projekt RED considered adding Diablo-style content to The Witcher 3: Wild Hunt, Tost replied:
We haven't seriously considered it yet. It's very important for us not to release content that becomes exclusive depending on where it's purchased [...] For us, this is a fundamental point: if you buy a game, you should get its full version.
Instead of in-game exclusives, Miles Tost explains, CD Projekt RED previously offered physical bonuses. As examples, he cited hoodies (clothing) and a card set. Tost emphasized that CD Projekt RED is «always open to interesting ways of cooperation», meaning the appearance of a conditional Diablo-style skin is not ruled out if it is available to all owners of The Witcher 3.
