True. Ideally, I'd like a PDF document that allows you to take one like any other Knight. Either as part of an Imperial Knight Primary Detachment, or can be taken as an allied Knight, but you never know. I just hope if they do so that they'll release the rules for including them in 40k sooner rather than later. I've got two Knights right now (Paladin and Errant), and I'd like to get a Lancer, Warden, and Crusader to fill out a full army of Knights without having to duplicate Knight versions.
