Long wall of text on Catsuka. So, the concept was originally Thomas Romain's, but Satelight's Shoji Kawamori (the father of Macross) said the project was not adapted to the japanese market, and was lacking in scope. Shoji Kawamori took over script writing and characterization, while Thomas Romain was free to do whatever he wanted with the visuals and the mecha design. Shoji Kawamori's objective was to break free from the traditional robot series he himself was the author for more than 25 years.
Then he goes on to say that a bunch of other famous and not so famous people joined, and sets a bit the stage for the action: a parallel Earth, a game inspired from street basketball, but using some transformable robots, and "freestyle" is a keyword of the concept. Well, nothing beyond young audience level in what he says, hopefully Shoji Kawamori can give it more depth. Later he mentions the series is aimed at teenagers and adults.
The 26 episodes series will air starting april 2009, and will be broadcasted during a night-time slot. There will be two manga series, etc.
This was a Public Service Announcement for non french readers.
