The Skink Priest’s OK, but I already have 2 and don’t need another one. I sincerely hope there will be at least one new Saurus sculpt or even a Kroxigor, as an all-Skink warband would be boring.
GW have showcased who the other Warbands are for this season of Underworlds:
Ossiarch were an obvious choice for a Warband this season because they’re the only Death faction to currently not have one, April’s warband looks like Bonesplitterz (who were due a Warband after the Beastgrave Destruction Warband was a second Ironjawz one for some inapparent reason) and June’s looks like Idoneth, who I completely forgot about as a faction that was missing a Warband. March’s one, however, is uncertain. I’d guess either it’s our first glimpse of the Umbraneth (though I’d rather see shapeshifting Shadow Daemons as GW originally talked about than simple Shadow Elves) as the Slaanesh Direchasm Warband teased the arrival of Sigvald’s Slaanesh mortal army, or a Cities of Sigmar Warband oriented around the Dark Elf Beastmasters, which would explain the creature skull as their emblem.
