Very happy - if a little surprised - to see it. I've posted elsewhere a number of times about a Dawn of War sequel or remaster. When we saw the DE get launched I figured that was it, so to see DoW4 announced was a great surprise.
I'm not getting too excited yet though. The choice of developer is interesting. KING Art Games made Iron Harvest, but they don't have the RTS pedigree that Relic has. It remains to be seen if they can handle something as high profile as Warhammer 40K; especially an IP with the legacy that Dawn of War has. We're going back 21 years!
