At any time, they could always choose to animate the Catastrophe light novels.

I am not even sure if there will actually be a third season. In the manga, it has been Ferid ruling the vamps of Japan and sending it all to hell (worst ruler ever). He and Crowley are playing with Mika and co. right now, but the plot hasn't gotten too far. The main characters have discussed rescuing, but that's not in fruition yet. If there is a third season and the anime returns to the manga plot line, they could give it a title about revival of the queen or something, but it is too early to say much for sure.
