Things like that are always difficult to judge...
Quick re-cap:
- Someone found Yonezawa's personal twitter in which she stated she stated she had a boyfriend for 4 years, they broke up and she's looking for a new one.
- This pic showed up:
- On her G+ she posted to leave Nacchan out of this.
なっちゃんに迷惑かけるのはやめてください
- Yonezawa arrived in SGP for their performance, but apparently she was all quiet.
So yeah, it's always hard to separate the facts from the rumors, but something seems up. I guess we'll have to wait for some official announcement.
edit: more pics appeared, but these are Nacchan related as well

Please note: the "Miichan" mentioned here is NOT AKB48's Minegishi Minami.
