Glad to hear that, Spiney

For my part, I've decided to sell off all my Blades of Khorne except for a Warcry warband. That's just enough to enjoy the models I want to paint, without having to paint 60 #@&%ing Bloodreavers with a 6+ save and 5+ Bravery.
Idoneth are definitely cool, and while Lumineth were the pointy-ears for me, I've definitely been tempted after seeing some of my local group's Idoneth players' models up close. There's even a war turtle in my local GW's display cabinet right behind all the figureheads from Animosity II.
Disappointed that the "new army reveal" was just confirming a new Hedonites book which was basically a given anyway. That said, there's still a bunch of Rumor Engines unresolved, so yeah, we'll see. You're not the only one hoping for vampires, and they were hinted at in Broken Realms: Morathi.
Likely won't jump into Hedonites myself until I'm a little further along on my existing projects, but they're definitely on the docket. NewGuy gave me an army premise awhile back based around a greater demon called "the Teller of Secrets" and the ruined homebrew nation of Druze. Three of my Stormcast characters are women from Druze, so the Hedonites would be a great addition to their rogue's gallery in my collection.
