I want those Skitaari, they look great. Less sure about the Ironstriders, they look a little cluttered to my me, but I'm sure I'll be able to do some conversions with these. I'm assuming this mean the AdMech are getting a codex, which is pretty flawless timing since I just got a job. Now I'm just worried GW will screw it up somehow. I wonder what horror of failed aerodynamics will come with this lot.
Also, apparently the Ironstriders are nearly perpetual motion machines. Could they not have just made something cool that doesn't violate the laws of physics? Plausibility isn't a bad thing, GW!
