Yes, CLAMP will be back for character designs, as will Akira Yasuda for mechs-- or rather, Knightmare Frames. And of course, Ichirou Okouchi and Gorou Taniguchi, who came up with the original Code Geass story, will be back for this new piece.
There are a couple of newcomers to the franchise: One Shigeru Morita, who did scripts for Mobile Suit Gundam Seed and a variety of episodes of Blood+ and Toward the Terra, will be on screenplay duty for the new Geass. And Kazuki Akane, who's directed works like Vision of Escaflowne and Noein, will helm the new series.
That's everything we got so far, except for these rather uninspiring images.
Nonetheless: hey, lookie, a new Code Geass anime! Who's dying to watch it and who's so done with the franchise?
