We’ve not even gotten the ACTUAL Codex: Orks and it’s Supplement is just waiting to ship!
“I just recieved word from someone who works for GW (higher up, not a red/black shirt), that there will be a codex supplement called Waaagh Ghazgkull. Obviously, themed around the warboss we all know. The book is listed as codex orks supplement, but it is unclear at the moment, if it will be like Clan Raukaan (so you need the codex), or standalone linke Militarum tempestus. It will be released soon, I assume shortly after the codex. It appears, that both books are already in the warehouse waiting for the day of release.
…it is centered around Waaagh Ghazgkull, and probably is a true Codex supplement like Clan Raukaan, for example. He was spot on with the Codex Collection, but a confirmation from someone else would be nice.”
