I've found out from Kano's site that there is to be a new ED theme for the third movie Truth Dawn by Savage Genius (Uta Kata OP/ED and a number of other anime since). The title is 「あなたのようです。」 which, being in Hiragana I can transcibe easily enough ("Anata no Yō desu"), but with no Kanji to indicate meaning all I know is that it means something like "It is your Yō." The online translator I use reckons it to be "It seems to be you."

I missed a couple of updates on the official site while I was away on holiday, but there were all about what guests will be at the Truth Dawn showings in September.
Other new stuff since last update to last entry:
Kiddy Grade 2 Pilot episode (Livejournal KG community)
Kiddy Grade movie (dannychoo.com)
The song is included on Savage Genius' second album, Sora no Kotoba, to be released on the 7th November. As with the last album, there is a limited edition version available with a DVD, which this time has footage from their performance at Anime Expo earlier this year.
