Rumours regard the senbatsu for SKE's next single:
Team S:
Matsui Jurina, Matsui Rena, Ooya masana, Yagami Kumi, Suda Akari, Kizaki Yuria, Nakanishi Yuka (7)
Team KII:
Takayanagi Akane, Hata Sawako, Furukawa Airi, Ogiso Shiori, Mukaida Manatsu, Yakata Miki (6)
Team E:
Kimoto Kanon (1)
Kenkyuusei: Suga Nanako, Matsumura Kaori (2)
& I believe Ishida Anna (KII), Kaneko Shiori (E), Matsumura Rina (KII) are out.
There's also some reasons listed in the source for the inclusion & exclusion of members. Most of the "major players" left off seems to be due to weak handshake sales; while Nakanishi, Matsumura, Manastu, & Yakata benefited from their strong showing in the senbatsu election.
The source seems to be pretty sure of Nanako's inclusion it seems, based on a g+ post, & the reason for her inclusion is due to strong handshake showing (for her generation? not too sure what it means.) Not sure how much truth is there to it but it information I guess.
Wasn't sure where to post this, as it seems like rumours
Move if necessary mod.
