Ultimate Campaign Guide

So I have searched through the forums for answers to the questions on mass combat ect. Ive noticed that the Kingmaker AP has some stuff added from the Ultimate Campaign on kingdom building but nothing for mass combat other then army stat blocks. Will mass combat be added to the system and I am assuming if so it will be added when the Ultimate Campaign Guide comes out?

Ultimate Campaign is out and nothing in it to support the Mass Combat other than a catalogue of special abilities, Feats etc.

Very disappointing :(
