I am sure at some point they will release a BG, however absolutely nothing has been said or released by SE in regards to PVP beyond the wolf's den. I would love a link to your proof of this (though in some capacity they probably are conceptualizing/beginning a BG) however the only mention of any form of PVP beyond the wolf's den is by people such as your self whom are purely speculating.
