With idols rising in female popularity, you are going to get large amounts of girls who auditioned because they want to be idols.... but if most of them are hungry for the moneyZ according to the judges, then you pretty much have an impossible audition.
Also, with Berryz Kobo's indefinite hiatus, I could see that maybe they are going to start their focus on a new KSS unit. It's tends to be a larger hype than a revival group.
