Hearts of Stone, the first paid expansion for The Witcher 3: Wild Hunt, hits stores tomorrow — digitally, at least. The planned physical version of the new content has been delayed, according to a post on developer CD Projekt Red's official forum.

Marcin Momot, the studio's community coordinator, wrote in a thread about the limited-edition boxed version of Hearts of Stone that "due to logistical problems, customers will be unable to obtain the physical edition of the game for several days after launch."

Not only is the special edition box meant to include the $19.99 game expansion, it also comes with real Gwent cards based on those available in the game. These cards can be purchased separately, Momot said, from a special site.

Also mentioned in the post is GameStop as the possible exclusive storefront for the retail version. "We are working with GameStop to fix this situation as soon as possible," said Momot.

The Witcher 3 players who don't want to wait around for a box to add to their gaming shelf can pre-order Hearts of Stone just in time for its Oct. 13 release. Just like the basic game, it will be available for PlayStation 4, Windows PC and Xbox One.

The next major update to the game, which previously offered free downloadable content, is Blood and Wine. An official release date has not yet been announced, but it's expected to drop during the first quarter of 2016.

Update: GameStop now lists the physical Hearts of Stone bundles for purchase on both PlayStation 4 and Windows PC. The Xbox One version of the set is still not available.
