Privateer Press has a couple new previews up on their website. One's for Hordes. The other is for Warmachine. Both take a model you sort-of know and then expand it out to monstrous proportions. Let's take a look.
First off there's the Grotesque Assassin. Note: that's "grotesque" in terms of the unit type it comes from. Though with that chin, extra spikes/bumps all over, and wings, it could just mean "horrifying" as well. After that is the Trench Buster. Basically, take an Ogryn, give him Trencher garb, and away you go.
