Update: Small interview with THQ (company developing the game).

While there is already a Warhammer Online game, it's curious the focus on the WH40k setting (Dawn of War II had recently it's first expansion, and more will surely follow) in detriment of the fantasy part. Maybe with the incoming 8th edition rules will the fantasy setting strike back?
