Got excited by the new Forge World teaser trailer: http://www.youtube.com/watch?v=1L2yt7IS0OY&feature=plcp
The Horus Heresy books look terrific! I wonder how the rules will compare to the old warhammer 30k fandex launched by BoLS a while ago? It'll be interesting to compare.
The release date *appears* to be UK Games Day. That's September 21st this year. Exciting times!
