We know the Playstation exclusives expire after a year which means we should be seeing the Dust Palace brought into the Nightfall rotation the day the Taken King launches but I'm hearing conflicting information about Undying Mind. A lot of people on reddit are saying the exclusivity for that expires at the same time but that strike was introduced in the Dark Below, not Vanilla Destiny which means it will have only been 9 months since its debut. Does this mean we'll have to wait until December before we have the pleasure of doing an Undying Mind nightfall? As a PS4 user, I can say that having content be Playstation exclusive isn't much of a benefit when they are only playable in Strike playlists and are excluded from end-game content. Here's hoping the "one year" rule on the exclusivity doesn't apply to the Expansion exclusives and we get to experience the utter chaos of an Undying Mind nightfall in September.
