Will The Jonas Brothers be all washed up now that Justin Bieber is the new teen idol?

The Jonas Brothers were really famous, but is their time all up now that Justin Bieber is the new teen idol? Im wondering because, this happens with mostly all of the teen boy bands. Like- The Backstreet Boys, New kids on the block and Nsync. And, when Justins time is up he will be replaced by a new teen idol too, do you agree? Because I am sick of jonas bros, they can't sing that well, and im not to fond of justin either. Im just not into the teeny bopper idol thing
