Trying to predict what girls Tsunku is impossible.
In the clip he says that it's okay if it's not many members this time since 9ki and 10ki were quite a lot. As long as the girl/s has the appeal of being a vocalist.
About Hamaura: She used to look like a small child but recently she grew a lot. She's gotten much better with expression so that one ends up noticing her even though she's dancing in the back at H!P concerts.
About Kishimoto: She has quite a positive personality and seems to be up for doing anything.
About Ichioka: She's not a very powerful girl but she has a character that they don't have in Morning Musume right now.
About Ono: She shows her full potential in dancing and her singing is stable. And since she's worked with Tsunku before she knows "Tsunku-rhythm".
About Oda: She uses her fingertips differently from how any H!P member has before. She has a volume to her voice too, even if she's not at her peak yet she can definitely grow a lot.
About Makino: She seems to be the kind of girl that if she gets into Morning Musume right now she would make herself get to the front.
I have no idea of what he means with that fingertip part... o.O
I want Sakura and Haruka. If he has to add three I would be fine with Yumeno or Reina... I think.
