So far we've gone through SM, CM, GK, and about to have DG. The only new models have been Primaris and Death Guard who both may as well be new factions so it is doubtful. On the plus side, Guard is the strongest faction right now. They won BAO, Nova Invite, and Nova Open. The only models they showed off were: Necromunda, Mortarion, and a Herald of Nagash from Sigmar.
