I'm not uninterested in Kislev, and suspect the motif could bring a lot of former Empire players, and some new players from W:AoS, back to the Old World.
As for rules, definitely more of the wait and see attitude here, and trying not to get my hopes up. Plus, here's hoping they don't just complete it as a project, and there's some momentum to continue moving forward in a positive fashion, although I'm not betting on it.
