Currently nothing can be said all depends on how good COD AW is from what I have seen and what I have read I think COD is shaping up good but I am bit worried about the competitive crowd.
Personally Destiny does not has the same feeling as what I felt with older Bungie games but it looks great. Campaign is fun but having open world sort of reduces the impact of an epic story and multiplayer in all honesty sucks partially.
But whatever we say both games will sell like hot cakes and Activision will dance and party hard.
Still Early Thoughts: COD>Destiny sales
