Not sure if this should maybe be in the modeling section, if so please move.

I've always liked Nurgle and the chaos legions, and I really like the new FW stuff being done for WE and DG. The stuff that FW has produced for them is just conversion kits, right? Does this mean that I have to purchase a box of csm\terminators and the conversion kits? This seems like an extreamly costly thing to do (around 35+ a squad). Is there others ways round this? Is FW likely to provide an option of a full kit like they did with the red scorpion sternguard?
