The latest issue of Play Magazine, speculates that God of War 4 could be a prequel (like PSP games Chains of Olympus and Ghost of Sparta), and could star - or at least co-star - Kratos' brother Deimos.
The feature quizzes two former Sony Santa Monica artists about the future of the God of War franchise, to find out more.
Asked if the greek mythology context was becoming restrictive for to the franchise, Cecil Kim, an artist who worked on the series said cryptically:
"Well, if you see the franchise is all about Kratos, yes..."
Kim didn't expand on whether Kratos would be joined by a second character on his next adventure, but added that Santa Monica studio's experience on five God of War games made him "confident" that Sony would resurrect the franchise.
So could God of War 4 be a prequel?
"Kratos's past is touched upon to an extent if you go read the comic book series based on the game," said former God of War concept artist Andy Park, now working at Marvel Studios on films such as Iron Man 3, Thor 2, and The Avengers.
"As far as the games are concerned, I'm sure the amazing writers of God of War can figure out a way to incorporate and expand on Kratos' past into future games if they wanted to."
