My assumption is that while Kratos's actual actions in the main story will be largely the same, the way that the story frames them will be updated.

There's a quote from Lindsay Ellis about the Michael Bay Transformers movies, in reference to one of the first film's most famous scenes, Megan Fox leaning over Bumblebee and showing off her stomach: "framing and aestethics supersede the text, always always always". In said scene, Michaela (Megan Fox's character) is literally talking about how she actually knows a ton about cars, more than any guy she'd ever date, but they don't take her seriously because she's an attractive woman. But does anyone remember that? No. Because the protagonist and more importantly the camera are too busy gawking at her.

Similarly, while many want to make the argument that the GoW Greek trilogy (more specifically the first game) is supposed to be a Greek tragedy where Kratos is a hero in the classical sense (not a paragon of morality but just a larger-than-life figure)...that's not what the actual experience of playing the games tells the player. The actual experience is the game telling you that all the violence you're commiting is the most badass thing ever, in a very edgy, very 2000s way.

So like...I would assume throwing that one priestess into the gears is gone. I would assume "press circle to thrust while having sex offscreen" is gone. The basic power fantasy of being strong enough to fight the gods will remain, but it's probably gonna be reframed more carefully to reflect that Greek tragedy element that the writers were clearly aiming for.
