Authors have to be vague with the new stuff coming out in general. Don't want to give too much away. But i can see him doing something with Yasaka and Rossweise with Issei at this point. Yasaka needs more story time for the later stuff to happen. So it makes sense for the readers. But yeah i do thing they are working on stuff behind the scenes for another season of anime. I think things didn't happen this year because he got sick. Most of the time when they do another season of anime they consult with the author of the source material to get their take on certain scenes that happen. Why source material usually slows down during a season of anime. Since the author has to juggle more then one thing.
