while watching a GDC 2013 video, there was a lot of mentioning of tigers; appearing in concept art and character development stuff. later in the video, it was stated that "Tiger-Man", a brainstormed playable race, was Bungie's last attempt at a tiger element in destiny, but it was then stated that and i quote, "it still may appear..." i agree that it is too early to tell for sure, but this seemed to me to be a possible hint towards a Tiger Man easter egg in the game.
