Have you not see the commercials saying that The ultimate Destiny experience is on Playstation? Besides, if you have an xbox, then you know that Activision has been giving out Call of Duty content a month ahead of playstation users for the past 2-3 years and will continue to do so with this year's game. Destiny is the one game where Playstation gets the content first. Meaning, that this stuff will eventually come to xbox, they've even said as much, but it will be timed.
