Yeah, that's pretty cool. It probably was a long time demand over at the IO boards.
The most interesting new feature, however, is probably the notoriety system. Witnesses you allow to escape alive will be questioned by the police who will in turn elaborate a sketch that will be published in the papers and allow people to recognize you in later missions. The sketch's likeness depends on how many witnesses have seen you. You can also be recorded on CCTV, which will increase your notoriety by quite a bit. You can reduce your notoriety by means of exorbitant bribes, that can take up a large part of what you earn in a mission, though. The game also features a monetary penalty for any clues left in the scene such as your suit, or any of your custom weapons. I believe in the higher difficulty levels, this increases your notoriety as well.
All in all, very good stuff.
