It's the tail end of the Kharadrons. with the Endringgers/ Skywardens dual kit being an expensive end to the troops. There are two specialists, the Aether-Khemist, who is kind of like a hazardous environment trooper and the very cool Ednrinmaster, who pretty much encapsulates all things Kahardron in one miniature.
In other releases, the much-anticipated novel Azrael by Gav Thorpe is out. Dark Angels had half a second of sun recently and have since disappeared. Also next week is yet another Shadow Wars "deal" - the Shadow War: Armageddon Collection is the Galvanic Magnavent and Ferratonic Furnace plus the rule book.
With 8th Edition 40K in the wind, they need to do something soon, because we had a flurry of releases and now not much at all, certainly seemingly no surprises!
