Telltale Games have announced that both The Walking Dead and The Wolf Among Us will be coming to the PlayStation 4. Both will be available to either download digitally or buy in a physical format.

It has already been confirmed that a third season of The Walking Dead is in the works but it is unlikely that we will see it for some time considering that Telltale is currently working on The Wolf Among Us season 2, Tales From the Borderlands, and of course a Game of Thrones episodic series. The Walking Dead season 1 and 2 will be released in October whilst The Wolf Among Us will see a November release date. The retail versions for the PS3, PS Vita, and Xbox 360 versions will also be released at this time.
