The list has a nice selection of things, with only a few things missing. Suprising additions are the Plague Furnace (mount for Plague Priest) and Bonebreaker (Rat-Ogre mount for Warlord).
Things that aren't included are Jezzails, Ratling Gun, Doom-Flayer, Poisoned Wind Mortar, Warp-Grinder, Giant Rats and Chieftain hero. There's also some mounts with the Great Pox Rat and War Litter.
A lord DLC with Ikit Claw and possibly Thanquol (though I'm thinking he might be FLC along with the combined campaign map) would make sense with most of these units being from Clan Skryre.
Some units that had me looking up my rulebook to find out what they are. Death Runners are the name for champion Gutter Runners while the Death Globe Bombadier is likewise the champion unit for Globadiers, Death Globes being a stronger Poison Wind Globe.
I have to wonder about items. Death Runners are equipped with Weeping Blades but I would like to know whether you can equip a Warplock Engineer with a pistol and the brass orb (A vaccuum in a sphere). In tabletop the Brass Orb was great for erasing powerful enemy units as it dealt an Initiative save or die under the template. There was also the Fell Blade that was stupidly powerful but slowly killed its user and Warpstone Tokens you could use to boost your magic points at a risk of taking a wound.
