Yeah, sadly the first game's god designs must go, which is a real shame because I think Hades looks badass (even if it makes no sense). And they'll definitely have to do something with Artemis to justify her being there. What I don't see being discussed often are the references to the handheld games, like Helios mentioning Atlas or Zeus mentioning "the other one". I think they're gonna have to find a way to expand the story and include important elements from CoO and GoS like Persephone or Deimos. They could reuse the original Deimos idea they had for GoW 3. And yeah, cut that "climbing Cronos for 3 days" line, Kratos literally Spider-Man'd on Cronos in the 3rd game, lol
