Even though it was 'revealed' last Sunday, Destiny will not release this side of 2014.
Activision had to release a statement to explain the release window after they practically revealed no details during a rather anticlimactic reveal teaser. "Activision reiterated that although Bungie's amazing new world was revealed today, Activision has not included the launch in its 2013 outlook and there should be no speculation or expectation of a different result." So there.
Destiny has been confirmed for current-generation and next-generation consoles, though a PC version has yet to be confirmed. More details here.
