I am not a Slaanesh fan , but I'll buy Sigvald, Glutous, battletomes and endless spells... and rest of the wave in a later time.
Also, no Newborn model.
What's more, I am really curious if there is a concept that AoS will get something like Combat Patrol boxes. If not now, with two new battletomes, maybe after 3.0 launches? Or maybe it's only 40k stuff for now.
