Which AKB48 sister group can be as successful as AKB48?

Lol, but unfortunately only due to its new infamy. On topic, I think HKT48 has that chance to overcome. Then again, its most popular members will be gone soon/are gone already, so I don't know. Second guess would probably be STU48 in the future. I mean, they've got all the freshness of Tsukiji fish market.

 

Bro, bumping old thread much? At least apologize next time
