Activision/Blizzard has posted their official press release. I've archived it here. Near the bottom they put a tidbit for Bungie fans with a penchant for rampant speculation:

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 you have it. You're not even allowed to think it's not true that Destiny won't come out this year.

Thanks to MDQuackers in the DBO forum for the heads-up.
