The Witcher - Preview @ CVG

The Witcher has been previewed at CVG, probably from the GDC demo based on some of the examples given.  Here's the introduction to set the scene on Sapkowski's world:

The elves are terrorists. The dwarfs are persecuted in ghettos. The biggest threat to the kingdom of men? That'll be another kingdom of men just down the road. The purest, noblest, greatest defenders of the land... well, there's not a lot of them, so the job of stopping random monsters from eating everyone is picked up by genetically twisted mutants. They're called Witchers, and you're one of them.
