There's been reports (or, at least one report on Moonphase that other people are commenting on) about a second series for Kiddy Grade. The original source was something Aya Hirano said during the 35th Suzumiya Haruhi radio programme, now online on the SOS Radio Shibu page (KG2 is mentioned about 24 mins in). I've not seen any news about this on Gotoh's blog, however in a recent interview, Gotoh did mention that his current project was a new anime.
