A plastic Kroxigor would have been great (and I certainly hope we do see some plastic ones at some point), but we do have two other Warbands with Monstrous Infantry models in them (Mollog's Mob and Hrothgorn's Mantrappers), so a third MI model would have perhaps been too similar to either of those in terms of mechanics (i.e. relying on the single strong fighter to defeat all comers and using the rest of the models as chaff). Instead we got a more balanced warband, which I think is more realistic because Lizardmen have always historically relied upon the Saurus and Skinks working together to defeat the foe, compared to Ogres, for example, where the Ogres themselves do all the brute work and the Gnoblars are just along for the ride.
Personally I think the Chameleon Skink is the best model - much better than the Blood Bowl ones. If only we could get a full set of them!
Now, what interests me is we're getting another teaser of the next Warband:
Who are these guys?
We already had a preview of one of their models and their faction symbol in a previous article:
I still think they're going to be Dark Elves, either our first glimpse of Malekith's lot or Black Ark Corsairs, given they've been causing trouble in Broken Relams: Morathi, long hair is a trademark of Elf models, they would fit well as a foil to the High Elves 2.0 in the starter box and their logo is a beast's skull (certainly in Fantasy Dark Elf society the Corsairs were renowned as beast killers as well as raiders). However I wouldn't be surprised if it was more of Slaanesh's goons either, as GW have gone Slaanesh-mad at the moment and the elegant cutlass swords look rather like some of the weapons on the new Slaaneshi mortal models.
