Na, i still think it'll make one last return next season (if it happens). It only appears during the "healing" scene with Asia/Akeno/Koneko, and that scene is TOO IMPORTANT to be removed. While they've changed/removed some stuff from the LN, they won't change any more major plot points. Yes, they removed the RG, but they used the Loki battle as it's replacement. I feel Loki will still make a return for the final fight.

Vali was suggesting that it's the destiny of the two Heavenly Dragons to fight, as the previous hosts have, which is why Issei says he wants to break that destiny.

And yea, in order to get back Loki, they'll have to break through the seal he put on himself, which will take time, since he is a god and all.

I still feel the major plot interests will remain the same, even with the changes they made with this season. I feel they're just experimenting....
