first-person stealth/action adventure, yay. Reads (can't say looks yet, no video or screenshots) very promising.

Let's say you've played lots of classic games, you do like Deus Ex and HL2. How can you not love this following quote?

"Dishonored is the antithesis of a edge-of-your-seat roller-coaster ride. It's a game about assassination where you don't have to kill anyone. It's a game about infiltration where you can set up traps and slaughter the entire garrison of an aristocrat's mansion rather than sneak in. It's a game about brutal violence where you can slip in and out of a fortified barracks with nobody ever knowing you were there. It's a game about morality and player choice where the world you create is based on your actions, not navigating conversation trees."

I think there was already a thread about this, here.

Ah sorry, got excited about this game and posted quickly, after not reading Dishonored in any thread title.
