I've got a Chaos Marine team on my desk right now. Khornate marines; no cultists. But playing with the list, I'm already planning a second one, which will be Alpha Legion with many cultists, based on the descriptions in the book 'Legion'.
Necrons, I can field right now, with my 2nd ed model army.
Scouts I have ready in a great many flavors.
And I've got so many other WIP 40K armies that have been gathering dust for almost a decade now:
IG, AM, Tau, (Dark) Eldar, Inq, SoB, Orks, GK, you name it. And all that's needed is a small team between 1 and 20 models?
Good thing I've got the book on its way...

And here's to hoping either GW or some enterprising individual translates all original Necromunda gangs and Outlanders to these rules, because my flavours would at least double then!
