Though Sony has not officially announced a sequel to God of War III, the evidence for the game is piling up. Recently, South African retailer BT Games (via Joystiq) has listed God of War IV as available for preorder.
The retailer's listing indicates the still-unannounced game will ship during February 2013, though it does note the date is provisional and is subject to change.
A Sony representative told GameSpot, "We haven't announced any future God of War titles."
This news is the latest speculation concerning a follow-up to 2010's well-received God of War III, which was developed at Sony Santa Monica. Rumors had suggested the game is due as early as September 2012 and might include a multiplayer component.
Following the release of God of War III, franchise producer Steve Caterson told Industry Gamers that though God of War III marked the end of the trilogy, the studio would likely craft more games from the universe.
If Sony Santa Monica is in fact at work on God of War IV, it will not be the only project the developer is presently creating. Earlier this week, it was revealed that the California-based game company is assisting Team Ico in building the long-in-development action title The Last Guardian.
