Somebody's managed to get their hands on a promotional poster revealing the complete new Mechanicus range, including the new cult admech!
The new unreleased Cult Mechanicus appear alongside the Skitarii in what appears to be a combined offering. GW have been moving in a direction of multiple books for a long time but this appears to be the first time different parts of the same army appear in different books entirely.
Personally I am not soild on the clunky big bipedal robots or the tracked ones in the middle. The aesthetics seam to be too bulky compared with the rest of the range. Will wait to see better pictures however. Thankfully, Forgeworld do direct alternates to them.
