UPDATE 14:05 BST: The Witcher 3 standard edition includes a raft of extras.
An image in the latest issue of MCV magazine, right, includes The Witcher 3 box art alongside some extras.
With the game you get stickers, a game map, a Witcher Universe Compendium, the soundtrack and game manual.
The image was first reported by VideoGamer.com and was believed to relate to pre-order bonuses, but CD Projekt community manager Marcin Momot has since confirmed the items are included in the standard edition in a post on the CD Projekt forum.
