Next week looks like we will not be seeing an Ork codex, but instead be seeing another single kit, big gunz. Of course this is based off what we have been told that there were three weeks left in the Ork release and what the last page in this weekend's White Dwarf says.
Please remember that these are rumors. I dont have the magazine, and these are reports that are coming in.

In the back of the WD is says "White Dwarf 20: Da orks get shooty (Im guessing big guns kit) Famous WAAAGHS and Hall of fame." So the Next WD seems uneventful really. The codex is no longer available online so that should mean roughly 2 weeks till the nex DEX which isnt new rumors.
