"The magazine states that Kratos will be the next PS3 character revealed, so if the rumor is in fact true, we should be seeing something soon. Also, this will be the first look at Kratos on next gen hardware, and possibly a first glimpse at what to expect from God of War III. Obviously if Kratos appears in SCIV, Namco has cut some deal with Sony, and could be sharing actual assets or character concepts from the upcoming PS3 exclusive."
