[OGL Manga] Scope of the Genre

I see OGL Manga is already listed in Amazon. Of course, that doesn't mean anything, as Amazon lists several RPG books by other publishers that not only don't exist but never will.

What I'd like to know if the approximate scope the game will cover, because manga/anime is as much a form as a genre and it has an enormous scope.
Yeah Amazon jumped the gun there, I don't even think it's on the schedule for right now even.

While I can't give anything definite about the book I'm sure it'll resemble it's OGL siblings in scope on the subject.
