@George:
Yeah, it did remind me a lot of Uncharted 2. Especially the jumping from pipe to pipe while things are blowing up and falling away all around you.
I'm there with you on the character movement taking a bit of getting used to. I don't know if it's the running animation, or the way the camera's set up, but I'm pretty sure it would feel more natural after time. It was mostly an issue during the first bit of the demo.
The facial animations in the demo weren't quite as good as in Heavenly Sword, but it's just a demo, so who knows. Looks like there are a lot of other gameplay elements not in the demo though, so I'm still really looking forward to it. Especially to see where the whole relationship between the two characters goes. The earth environment looks awesome too :D
