The Witcher 2: Assassins of Kings Questing Developer Walkthrough Videos

GameTrailers provides a trio of the Witcher 2 gameplay videos guided by senior producer Tomasz Gop. They are new as far as I can see, but note they're based on a pre-beta build. Part 1, Part 2, Part 3.
Part 1: Enter a small dwarven town and move on to the tavern for a fantastical night of ruckus!

Part 2: Consult an expert knowledge on monsters, and maybe humans and elves, too.

Part 3: Engage a number of adversaries near a wooded pond and a creepy cave.
