Non-traditional gender roles

The January 2007 issue of "Japan+" magazine contains lists of the occupations most aspired to by Japanese school children (as identified by two surveys).

Number six on the boys' top 10, ahead of videogame programmer, chef, professional basketballer and policeman/fireman, is "comic writer/illustrator".

"Comic writer/illustrator" also appears on the girls' list - at number three! Only kindergarten teacher and nurse are seen as more desirable vocations.

I find these results astonishing, even for a comics-obsessed nation like Japan. Can I infer that there are currently or soon will be more women producing manga than men?

Would someone with more knowledge on the subject care to comment? Sis? RS?
