The Ork codex is rumored to be up for pre-orders on the 21st, and of course we expect a limited edition or two to be a part of that release. This rumored bit comes from dialogue back and forth about whether or not a supplement will be coming out as well.
Please remember that these are rumors. The rumored supplement at this particular time is with Ghazghkull Thraka.

I've heard there will be a limited codex with an supplement included.
