Project, more than a year in development, to include unspecified new artwork

The
Yotsuba Studio homepage has
announced on Monday that a new edition of
Kiyohiko Azuma's
Azumanga Daioh! slice-of-life school comedy manga will be published to mark the 10th anniversary of its serialized launch in Japan. The project has been in development for over a year. The studio promises new exclusive artwork for the edition, but does not specify if the new materials are new cover illustrations, new interior artwork, or new manga installments.
ADV Manga published the original work in North America, while its
ADV Video sibling released the anime adaptation.
