The article also notes that The Witcher 3 may import save files from previous Witcher games. Developer CD Projekt Red tells Joystiq that it would like to implement such a feature, though the challenges presented by new hardware could make it difficult. Specifically, considering the game will debut on entirely new consoles, including the PS4 and presumably the next Xbox, such a transfer could be impossible. Still, the developer is looking into the possibility.
The Witcher 3: The Wild Hunt is slated to arrive next year.
