I played the demo on steam today..

Great premise to the game. The preview on the website is actually more exciting to watch than it is to play the demo. That is primarily because you are very limited in what you're able to do in the demo.
I'm dying to find a new game to play, but I'm not sold on this quite yet. It reminds me of Thief, which was a great game, but failed to keep my attention. I wonder if anyone out there has seen more of this game to give a better view on how it might play out.
