Personally, I'd like to see some work on 'solid stats' for both GK and individual Inquistor models........
What works for 40k should work for SH, eh? They're the same thing after all......just different in 'scale of effect'...if ya get my drift...
While 1st ed rules for SH included GK's...the fluff from the same period stated that the 'Grand Master' of the GK is "traditionally a member of the Inquisition" ......... Something to go along with the RT era figures...Inquisiton and GK's now oop, eh?
This befor the GK became their own '40k models playable chapter'. Once upon a time there were only several IQ and GK models available (rogue trader/40k)
What I'm personally interested in is combining all the good stuff in order to create a 'Grand Campaign' in which it's not just hulks that are the 'field of battle' but possibly also hive-cities and other constrained areas of combat, different from a normal 40k table battle, eh?
To ME the whole part of having mix and match board sections is to be able to create a grander and very much larger map-world....one that can be used to create any situation imagined!

@Doghouse;
I'm also in favor of Chaos Termies, lower force groups (power armor, orks...etc etc......
The rules should encompass ANY and ALL , not just the 3rd ed figures....
Anyone that doesn't expect GW to start posting rules for all of these simply hasn't watched them do it the first time, LOL!
SH freaks worked on GW for YEARS about new rules, and got 'death watch' in return.
Now that the 3rd SH has rolled out.....Tell me you don't think that every group that has an expansion rulebook for 40k wont get one now!!
GW has now issued BA models, lol....In an effort to sell more, they're not going to sculpt every other Astartes, Ork and Chaotic?
Yeah, right........
