Finally played the demo.
Horrible first level, to be honest. The presentation in this game is ways off from matching its inspiration, and frankly I'm not surprised at all it runs at 60fps,
it looks like a freaking PS2 game. I appreciate the fact that the team aimed for 60fps, but I think they sold these consoles short. The gameplay mechanics offered in the demo are very simple-minded(reminds me more of the first GOW1, I find it hard to believe people actually like this more than the GOW3 demo), and like others have said it fails to capture the feeling of brutality you get with Kratos. Actually, despite all the self-hype from EA this game doesn't really feel all that violent. BTW the boss fight against Death was really boring, I don't quite understand how did this guy managed to defeat Death. DEATH. But okay.
Based on the demo this is a definitive pass for me. Releasing it so close to GOW3 just makes it worse. I guess 360-only owners will get their Kratos fix with this game.
I noticed they changed Dante's double jump to a somersault, at least they're trying to improve some things from GOW.
