Ps4 stuff is exclusive because Sony paid to get the exclusive content for their console. Bungie probably doesnt favor the ps4, they just gave sony the exclusives cuz sony paid money. And xbox got a lot of exclusives. The ENTIRE halo franchise, probably one of the largest franchises ever made, and a few other things. The exclusives ps4 gets for Destiny are all dlc's early, and some guns. Does that match an entire franchise? Not really. So calm down and let ps have some fun.
