unlocking other provinces & Knight school

[Toho]

Ok so the only experience I have with Warhmmer is the Warhammer mod on total war.
However I remember there were various knight orders similar to the Reiksguard.

Are there any plans to make those units? additionally any plans to unlock the provinces?

I mean best case scenario I can just play as all the provinces as one faction with each province keeping their individuality (when we merge) but.... I guess unlock those factions would have to do... right?

There are buildings for two knightly orders in Carroburg (Knights Panther) and Talabheim (Knights of the Blazing Sun) - they produce generic Empire knights, but have other bonuses.

I will be willing to bet that these will be the first candidates for the "unique units" that they've mentioned as FLC
