Saka Cataphracts are being worked on.
The Autumn release will likely be delayed for another 1-2 weeks; Tux/alin lost his hard drive in a crash and several crucial second release units with it. It will also give the rest of the modeling team some extra time to finish off a couple more core factional units, like the Bedouins, Indian Tribal Levies, Oksywie Swordsmen, etc.
