Source seems really shakey and... Honestly? I can't see sony doing this. Kratos has become top sad dad that everyone loves. Going back to mass murderer, rampant misogyny, and questionable consent undermines their brand. Greek kratos had to flee to a non extradition treaty pantheon for many reasons
I also question how much people would actually want to play those at this point. They were b tier spectacle fighters at the time and the overall quality has very much been stepped up in the past twenty years or so
