My guess is they will very much ride the coat-tails of GW. Hell look at the name of the recent contest for the dwarf release. "Win a [white] dwarf?" ha ha ha... they aren't even trying to hide it.
I have no idea if it's any good, but I'll bet they wrote the rules to their tabletop game just so they could defer some of the eyerolling from GW.
Some humans from them would be nice, but we're also starting to get some nice human plastics from Perry. Maybe ratmen would be cool... would be nice to have a Skaven army for less than $500.
