I don't think DxD being born from great red's and Orphis power (not to mention being the name of the story) is going to lose any importance to the story, rather the opposite. As for ExE I am inclined to belive it will be his sub-species balance breaker. Not a raw power type power up like DxD but a better way of using it. Options as I see it 1. a more stable form to use DxD (boring) 2. A new technique born from Issei's use not borrowed from Draig/Albion (better) 3. A form born from his evil pieces influence and his desire to protect his ladies, not a direct power up but a way to resonate with his actual peerage members creating Crimson Dragonnar for all at once. No basis really for the last but it is my favorite.
