Agonzale and cutie,
since you were priority waitlisted it could mean that they will reconsider you people when space comes available or its a sneaky way of making you an "honorable mention" Because some places waitlist without ever considering taking you off they figure since you weren't rejected you'll keep your other options open hope for the best and be happy that you were not immediately rejected. This is sad but true ¬e: this idea was quoted form a UPenn admissions director him/herself.

Sorry to give bad news Just hope for the best and keep calling to promote yourself and let them know your still interested.
