It was there a couple of weeks ago, and the August
PDF update brought everything into line with the
IG codex. It's possible they have withdrawn it temporarily if they are out of stock of the current print run and may be planning to reprint it with the updates from the
PDF, I know they're going to do this with
IAv5 as they won't release the
DKoK updated list as a
PDF until the new print run has been done (apparently they're still waiting to sell the remains of the last
IAv5 print run which is just crazy!).
Mort, here's the
PDF if you're just after the rules update.
