I am quite concerned about the silence going on for this epic historical story! In addition to many other anime that seriously need to be finished properly but have just been neglected as they are getting really, really good besides this. They all deserve a third season and many more and/or movies:
Cardcaptor Sakura: Clear Card
Rave Master
Raven of the Inner Palace
The Betrayer Knows My Name
The Dawn of the Witch
To Your Eternity
Vampire Knight
Yashahime: Princess Half-Demon
I mean a hiatus cuz the manga is still being made (Natsume's Book of Friends) I get, but not doing the rest of the story on screen is just too much!! Why make 'em in the first place if they refuse to finish the story?
Or do it in the form of movies, like with Sailor Moon Crystal, The Quintessential Quintuplets and The Eminence in Shadow.
