Now if your taste is more in the Imperial part of the galaxy, well you're in luck; Codex: Imperial Knights is here! Available in Stompy Stompy Collectors' Edition and Tally Ho Standard Edition, these add new rules and more to the battlefield monsters that are the Imperial Knights. There's also the Imperial Knights Datacards, but no dice for you.
Also in Warhammer 40K-land, War Zone Nachmund: Rift War, as new "narrative supplement" (not sure they have used that term before) is here - in both Reign of Terror Collectors' Edition and Event Horizon Standard Edition.
In books, your friend and mine, Old Kath gets a new tome, The Triumph of Saint Katherine in hardback, the paperback version of the Space Wolves The Helwinter Gate is here (just in time for it to get chilly in the southern hemisphere) and volume two of The Chronicles of Malus Darkblade in paperback arrives. We do wonder if Maleus Darkblade might get a shiny Collectors Set at some point...
