UPDATE: A representative from developer 343 clarified one interesting facet of the game regarding console exclusive items. In addition to exotics that exist on both Xbox One and PlayStation 4 version of Destiny, we can confirm that Xur--Destiny's shadowy salesman--can sell upgrades for PS4 exclusive weaponry, specifically Hawkmoon and Monte Carlo. Previously, it was thought he would be unable to do so since his inventory was identical across both platforms.

I can kinda understand accidentally putting Bungie into a Halo related article. But I have no idea how you could make this mistake.
