It's not known information.But i hope she will reappear in the Best Wishes,because she really rocked and i want her Piplup to be evolved into Empoleon if she will appear...
Update (2012)
Dawn does guest star in the BW series, along with Cynthia. Sadly no, Piplup doesnt evolve, it remains as a piplup.
