If you want to see more of 2K Games upcoming third chapter of the Mafia series, you're in luck, as a GDC presentation by Hangar 13 Systems Designer Seth Rosen included a few screenshots.

The presentation was about "adding life" to a game, in the form believable NPCs controlled by the AI, and the screenshots focus on that as well.
