Yes. They have done all of Geoffs models (or at least most) in his current collection. They run the largest 40k event in the world and also work directly with games workshop on their game.
Also, it is most likely Reese Robbins that will be in the game as he's a huge nerd on 40k lore (moreso than his business partner Frankie who is into the competitive side more) and Reese is also into RPGs a lot.
Reese was in Geoffs show Fanboys on week two I think.
