A lot of it does sound like wish listing, esp some of the special characters.
They may do something like the grey knight box where one box makes many, but the cult troops are waaaay to different to do that.
They will release a big toy to go with them, most likely this daemon engine thing, maybe a defiler variant?
I can't see three books being released, Maybe a cult book (ie the core four) and a legion (the other main 5) book.
I hope they have characters unlocking certain things BUT as long as they aren't unique characters like the SM codex. I like d the concept of the SM codex but not tat you need a SC to have a CF list, or RG list
Proper excited about the prospect of a new dex! I'm not fussed who writes it out of kelly or ward!
