I like the departure from the original Orlocks. They always seemed to be the blandest of the original gangs. It was too easy to just parachute in Catachan parts and have them fit...there was no real different identity to the Imperial Guard.
These guys though? They're lovely. Not Escher or Goliath lovely, but they're a totally different aesthetic and that suits me down to the ground. Really high quality miniatures with plenty of unique detail. I love that GW are incorporating the role of the gangers into the model...that is, there's a reason for Van Saar wearing the environment suits, Goliaths look as though they could be in a forge all day etc.
I can't wait to see what they plan to do with Delaque, Van Saar and Cawdor, let alone all of the additional factions that have been represented over the years.
