This came in today and while it does not give a lot of insight to what is coming next, except maybe the Malign Portent Champions, there could be something with that 5th Battletome. Sounds like a good mystery......

I have a friend who is a gw store manager. When he was last in nottingham for a meeting about the soul wars release, he was told the next 5 battletomes were already done and awaiting release. He was told that each malign portent champions would be getting a release. He was also told battletome 5 would be something completely different.
My prediction is that darkoath will be next because of the endless spell.
