Lots of rumors still floating around... and we have no idea what else is to come.
COuld be the datasheets coming on the website will have all that in it. Could be that it's slated for an expansion. Could be never coming.
We don't know.. I'm hedging my bets and just investing smartly in my hobby until then. When it comes out, I'll be able to play without buying if I want to see if I like it.
If I don't' like it, I imagine it'll be Kings of War 2 or a community WHFB 8.5 project.
We'll have to see. Lots of commentary on the Youtubers Warhammer Fantasy community, might check that out to see what the WHFB as a whole is considering - https://plus.google.com/communities/108169253575872689070
