It is expected to be announced today that an agreement between Warner Bros., JK Rowling and Akira Toriyama, the creator of Dragon Ball, has been reached for the development of a Harry Potter anime TV series to air on ABC Family in the U.S. starting in the fall of 2012.
Although they have not yet been made public, HPANA has learned that the basic concept drawings have Harry looking a bit like a young Goku (without the tail); Dumbledore looks like a cross between Master Roshi and Bulma's father; and Hagrid looks a bit like Dragon Ball Z's Ox King.
Rowling has apparently requested some minor changes be made to the renderings before they are released. We will, of course, post copies here as soon as they are made available.
(A live-action Dragon Ball movie is slated for 2009.)
UPDATE: Further information and even some initial sketches are now available online.
