No additional details were provided on the title, which was hypothetically mentioned by God of War II (PS2) director Cory Barlog during a launch party for the sequel last spring, and then confirmed after Barlog left SCEA in the fall.

"If we were to do a God of War III [on PS3], then it would finish this massive story," Barlog said during the launch event. "We've always imagined God of War as a trilogy, but the PSP game very much ties into it."

The tease of another God of War title within the packaging of the series' latest entry continues a tradition that began with God of War II, the manual of which confirmed the long-rumored PSP edition. However, the God of War PS3 ad fails to specify a tentative date as the PSP one did.

Developed by Ready at Dawn with the participation of SCE Santa Monica staff, God of War: Chains of Olympus, the franchise's first PSP outing, ships to North American retailers on March 4.
