I hope they switch from making warcry bands for Chaos to churning them out for DBC. --Saying this as a devout chaos collector, we have enough warycry kits!--
This could provide the broad flavor and fluff people seem to be craving. Especially since you can continue to mix up the races (species?) that are in the box -a la beastmen/dwarfs showing up in chaos warbands
The only issue I can see is how to justify the infighting: of course Chaos dudes fight each other, why would squads of Order dudes from the same faction brawl?
Unless they were 'underworld' operators. I would love to see fantasy underground mafia style thugs, who sometimes get hired as mercenaries for DBC battles?
