Ofc the rules will be the usual afterthought, 370+ pts each is either too cheap or too expensive (depending how strong is their Invincible Behemont special rule) and everybody but 'nids will get it but on the positive at least GW has managed to turn the weekely WD into something useful giving us the rules to boot.

Personally I'm not impressed with the miniature, I know others might end up drooling over it

Update: According to the rumours Knights can be taken in groups of three! In a regular game that's a disaster on the other hand it makes a cool scenario, e.g. Tau ambush a Knight hunting pack.
Update2: For SM players there is also a Codex: Legion of the Damned coming too.
