Furthermore, the cash cow goalpost of the manga media now is One Piece, which racks up 100~150 million per year on Japan ALONE and outsold Dragonball years ago (and let's not even talk about the absolute batshit insanity around One Piece that has taken Japan by assault). That's what mangakas and manga magazines are after now, and even some have emulated aspects of One Piece to try to steal some thunder (Kishimoto included, with the failure of a humor he has been coming up with since the Armadillo Dick incident). I'd even dare to say most of them have no idea One Piece lacks the punch it has in Japan outside of it borders.
So I'd only find the claim of your friend at least veritable if it was a comic book author from the US/Europe who would want to buy Dragonball and make it a cash cow outside of Japan. Or a mangaka/magazine on the brink of bankruptcy and desperate for a last stand.
Not disagreeing with you one bit. But it's been proven that if a studio/publisher wants to make money, they do it outside of Japan. That's why I'm not including One Piece with Bleach, Naruto, and Dragonball. One Piece basically sucks outside of Japan compared to those three. It arguably has more die-hard fans, but definitely not as many casual fans. Also, if you take into account inflation, considering what Dragonball was pulling in over 10 years ago compared to today... all it is going to take is a decent storyline and someone will try to push it.
Remember Dragonball: Evolution... a promising development with potential that was brutally murdered creatively and acting-wise.... It's happened once already.
