Some notes:
* Looks like Death will get a points discount for taking max units to bring back that "horde" vibe.
* Flesh-eater courts get a "delusion" that provides a minor bonus, and something called "Feeding Frenzy" which we don't know yet
* Nighthaunt get a deep strike
* Vampire Bloodlines for soulblight
Not what I was hoping for (hordes don't appeal to me, and I had hoped
FEC would get something that would alleviate the problem of killing characters makes the army useless) but I'm still excited to see the rest.
