I'm really intrigued to see how they are going to handle Hashut in this new setting. In the Old World, he was very much just the god of Chaos Dwarves, but sort of hinted he could be a powerful Daemon rather than full god.
I wonder if he'll be promoted to full chaos god along the lines of the Horned Rat?
Will he get his own Daemons, K'Daai style elementals, a greater Daemon/verminlord style avatar?
Could the real Dark Masters be something other than big hatted dwarves? Bull Centaurish mutant centaurs being how they look now?
So many possibilities, I cannot wait to see what they've got planned.
