Man, I was randomly checking up on the site, and I suddenly became very apprehensive.
The director is Masakazu Obara, which is VERY good. Given his affiliation with Mai-Hime, I'm guessing Studio 8 from Sunrise will do this, and with the current amazing record of Horizon, I'm sure the animation will be top notch.
BUT
Series composition is Hiroyuki Yoshino, not sure how I feel about this. He's like on the opposite end of the spectrum for me. Either I love him or I hate him to the core.
