Earlier this afternoon, Cory "Mumper" Stockton revealed a new wild battle pet
coming in patch 5.3: the Unborn Val'kyr. If we can all ignore
the creepy implications of its name, this will likely turn out to be an awesome addition to everyone's pet collections. Even if it turns out its battle abilities aren't very impressive (and we don't know yet either way), who doesn't want a tiny little val'kyr following them everywhere?
In addition to the Unborn Val'kyr, patch 5.3 datamining has revealed the achievement Raiding with Leashes II: Attunement Edition
which will add pets to Burning Crusade
-era raids, much like those added to classic WoW
