Well it's gonna air in just a few months. According to
THIS, it's been given a loose release date of the spring. It will be directed by Kiyotaka Isako, and the character design is by Akira Kano.
Isako had his hand in Comic Party, Maze, a few pokemon movies, and Virgin Fleet. Kano had his hands in Detective Conan: The Fourteenth Target, Digimon, Hoop Days, Initial D: Fourth Stage, Street Fighter 2 the series and the movie, the first Tenchi movie, and Urusei Yatsura: Always My Darling.
