Sega, Creative Assembly, and Games Workshop have collectively entered into a deal wherein Creative -- known for its Total War series -- will develop multiple titles based on the Warhammer universe.
This isn't to say the Total War series is going away anytime soon. Rather, a Warhammer team is being set up alongside the Total War, Alien, and mobile teams, so you'll get a bit of everything.
Creative's studio director Tim Heaton describes this as a "dream project".
It should be noted Warhammer rights still currently belong to THQ.
