^well, the current AKB won't take a risk kicking one of the new kami7 and the "Legendary 1st Gens" from senbatsu so what's left is the last 6 position if it's 16-nin senbatsu.
But even though I'm Mayu oshi, I agreed with this Sayanee-center thing.
Honestly, AKB needs more "dark song."
Dunno, Rena has Nogizaka. And Milky has SKE. Appearing in 3 senbatsu at the same time would be a bit too much a way too unfair, IMO.
As for Sayanee centering an AKB single... well, it was management who put her as number 1 in the official election photobook, so I'd say they have big plans for her. And with the leap she made this year, it would be plain stupid to ignore it and not use her momentum.
