Who cares, they're only chained for two more albums (presumably 2 more years) and after that they can break up. I'm just glad Bieber got punched out so badly. His time wasn't even up like the Jonas Brothers, and he was replaced so swiftly.
Don't count him out. There's still chance he could do big numbers in the future.
His music is a billion times better than theirs and the public loves a good comeback.
