Gotta go to class right now, but to sum the Akito parts up: he explains their philosophy is "to create something fun". Their intention with Akito is to "expand the Code Geass world". Instead of Director Taniguchi's "masculine literary style" (lolwut), we will have Akane Kazuki's "delicate literary style" o_o and since Akane analyzed the special features of Code Geass, Kawaguchi thinks the resulting new content is "extremely interesting".

No mention of the format yet, I think, but considering how long it's taking and that Kawaguchi also mentioned a few weeks ago in Newtype that they are veeery busy and aim to make 2011 "the Code Geass year"... Well, it should be something big enough?
