THQ tweets that March 12 is the release date for Warhammer 40,000: Dawn of War II - Chaos Rising in Europe, saying: "Chaos Rising release date confirmed - start your path to corruption from 12 March in Europe." And in a subsequent tweet add "Release date is 11 March in the US." The UK product page for the RTS expansion now reflects this with a listing of a 12/03/2010 release date, and but the US Chaos Rising product section has the same date in US format "03/12/2010," which is a day later than specified in that tweet. The add-on was announced for Spring 2010, which does not begin in the Northern Hemisphere until March 20.
