I don't think it's coming back and I haven't played for about a year and I was wondering that if you can't attack people in the wild then why do they still have levels in the wild?
Yeah... it's defintely not going to come back exactly the same... but there is no doubt that some form of PKing (not BH) will arrive, since numbers have dropped, and have only slightly increased due to HD. I'm thinking that they'll defintely have some kind of limited PKing (can only bring certain amount of items).
