I'd put real money on the Warriors and thunderer/quarreller kit being retired. It's one of the oldest kits still in production. And you can guarantee that a solo Dwarf force will be even more hampered by a new premium price, since technically we have access to all kinds of magic now (never mind the fact that most Dwarf players don't want to use any of it, they are still going to bake-in the cost). They already increased the price on Warriors because they were seen as too efficient in a Grand Alliance Army. Playing solo Dwarfs is going to be even more of an uphill battle than it is right now once that book drops.
EDIT: Sorry for the double-post. The site didn't show my first post went through, then suddenly it was there.
