Major update on the official site. They're going to start promoting this with the end of Unicorn. The final Unicorn chapter will have a 90sec trailer attached to the screenings. Lol. Sunrise isn't wasting any time.
The staff listing is.... erm.... interesting.
Chief Director: Yoshikazu Yasuhiko (Origin manga author)
Director: Takashi Imanishi (Sunrise CG producer)
Character Design: Yoshikazu Yasuhiko, Tsukasa Kotobuki
Script: Katsuyuki Sumisawa
Unit Directors: Kiyoshi Egami (directed some Yamato 2199 episodes), Ichiro Itano (only seems to direct CG stuff these days)
Chief Animation Director: Hiroyuki Nishimura (Little Battles Experience)
Chief Mechanical Animation Director: Takuya Suzuki (Valvrave)
Music: Takayuki Hattori (Slayers, Code:Breaker)
Yeah, I think all the mecha action are likely to be full CG for this one. If you're expecting 2D mecha animation and stuff like Unicorn, abandon all hope now.
