No part-timer or even vet (like Cena) is gonna end the streak. That's why I think this match is overhyped. It will be entertaining, but there's no suspense to it. It certainly wasn't enough to carry the card, which is what they would've have to resort to had they not inserted Bryan into the title match.
It will either never be broken, or it will go down to an up-and-coming star that they see as a "can't miss". In other words, if it is broken, it will be broken by Bray Wyatt either next year or at WM 32 in Dallas (Taker's home state; perfect place for him to retire).
