That ship date is still scheduled for May 17, a date that CD Projekt announced several months ago. The game, a sequel to the million selling The Witcher, will be released in retail stores in the US via publisher Atari as well as download sites. However the CD Projekt owned GoG.com will be the only place to download and purchase a DRM-free copy of the game.
