Witcher 3 - Announced for PS4
The next Witcher game will come not only for the PC but for the PS4 too, said CD Projekt. And of course for all next gen consoles. Simultaneously. So await an XBox 720 announcement soonish.
Current gen consoles aren't mentioned, but it would probably make economic sense to port it at least to the XBox 360.
Found on GamersGlobal, but other sites also ran this.
