Looks like Ubisoft resurrected this expansion after Sierra was dropped during the Activision Blizzard transition. Glad to see it is going to come out as the original was one of the best games of 2007. Still has the best graphics/engine of any RTS/RTT to-date, although I'm sure DOW2 will change that next month. There's also going to be a Complete Edition released simultaneously that has both the original and expansion.
