Dwarfs can still make a good list thatll match up to the new books. I've had my Bret's out recently and they don't match up at all the core ruleset combined with overpriced knights with rubbish stats makes them too fragile. There is too much stuff that ignores armour leaving small units that can't deal with standard infantry even if you get the charge. Unfortunately those sort of things don't make Gw business decisions dwarfs seem like a Gw choice due to popularity and a book that's easier to rewrite than wood elves or Bret's. I can see Gw having chaos as a relatively high priority as they have good sales. That and they still work with the current ruleset meaning itd be a good earner. Tbh it's all speculation but with the emphasis on infantry blocks dwarfs and chaos seem like easy options for them.
Edit: completely agree with the whole warshrine thing it fits with the current way books are being made. Fairly basic standard troops that are made better with shrine style units and characters.
