Forgeworld appear to be running out Tamurkhan: Throne of Chaos. Once its gone its gone, so no more reprints i'm told.
This may or may not affect the future of Chaos Dwarfs attending tournaments, but I can almost hear the "its not a real army" camp firing new shots already.
I have emailed Forgeworld asking if the Chaos Dwarf army will continue to be supported after they sell out of the book, and whether the rules for them will become available to download and/or updated.
This plays into what I have been told recently that Forgeworld will not be looking at WHFB again for at least 2 years.
