Welcome to Librarium Online!
The new deamons units are now on the GW website to advance order. There's a plastic deamon prince, plastic horrors, plastic seekers and a metal model of the Changeling. Check it out, they look pretty cool.
I was very surprised to not see fateweaver. :p He IS in the fantasy rulebook. :/
I asked about him today, apparently he's coming out in the later part of the month or something.
