I believe I also recall him hinting at a certain level of destructibility in the environments, or at least them changing over time. So you may hide in some building at one point, but later on it's been blown up and there's nothing but rubble now. It's still a stealth game like the others, but it sounds like he's aiming for a much more immersive experience.
