About Kanna, Hayato and Angelic buster

I was forced to stop play just as Kaiser was released and sadly I missed Angelic Buster which I was soooo looking forward too. Then I see that two additional classes are released which also seem fun to play (I actually have 3 free char slots by coincidence) and I was wondering if there has been any official statement of when they will return... I can't wait!
