Skimmed through the presentation at TGS; can't listen too well or read kanji so what I got was limited. But anyway, in the distant future, there will be...
...a 2nd collab event with Koihime Musou. Xun Yu will be the event SR kamihime. Cheng Yu is the event SSR eidolon. Sun Ce (SSR) and Zhao Yun (SR) will be the limited gacha kamihime.
...magical release Baal (SSR like the others)
...Samael, a new SSR kamihime voiced by Kitamura Eri
...and probably the most interesting thing is the announcement of a 4th event type, tower quest

Oh, the major announcement isn't even related to Kamihime Project specifically. It's Techcross (the developers) announcing their next dmm game, Unitia. Pre-reg is apparently already up?
