There are a couple of sketches
in the set reports section at GB, no actual photos yet. The description is correct. The abdomen is basically the Cybus abdomen. The chest piece reminds me of a harness, with the disk in the center having an iris (maybe a weapon). The head is very Tomb of the Cybermen. The legs are reminiscent of the Cybus, but leaner and toned down. The arms remind me of the Sontaran uniform.
