I'm more interested to know if anyone is planning on by this weeks White Dwarf, and what fluffs in that.
I bought this weeks' WD, issue 4, if that's what you mean? It's a bit light on background for the Knights. The direction they've gone in seems very close to the original Andy Chambers background from Citadel Journal, back in the day, but details are thin on the ground.
Broadly speaking it appears that there are three types of Knight subfaction: Mechanicus aligned knight worlds/houses, Imperium aligned knight worlds/houses and "freeblades," a mercenary third faction. One imagines that this spread of factions gives virtually any human army the chance to have a knight attached to it: Astartes, Sororitas, Guard, Mechanicus, Inquisition etc etc. Presumably this also includes chaos tainted versions of the knights.
There is, apparently, (according to BoLS) a Codex coming out for the knights, too. I'm looking forward to that. It's due on 8 March, alongside at least 2 other Knight-focussed books.
All this is fantastic as far as I'm concerned. I love the new Knight miniature (even though I can't afford it at the moment) and I've always been very fond of the Knights as a faction. I actually have about a dozen of the original Epic scale Knights, with a broad mix of lancers, Knights, Wardens, Castellans and a Baron...
