There's going to be a new ending theme - "Anata ga Koko ni". Presumably, it'll be for a new season. It's by Rie Fu, and the single will be released on October 24.
For the record, Rie Fu did songs for Bleach and Darker than Black (DGM seems to be borrowing artists from both animes. xD). Hm, I wonder if this means we could get High and Mighty Color or UVERworld doing themes? (Oh... UVERworld is releasing a single in November, too. =D *crosses fingers*)
