The statement continues: "It is their hope that Prince will reconsider his position and allow these fansites to continue their existence without constant threats from Prince and his attorneys. Should this not be possible, the fansites are fully prepared to defend their position in the proper court of law, as well as fully prosecute any claims to which they are justly entitled."
There has so far been no official comment from Prince about the dispute.
