Dear poster, Please keep in mind that these are TIMED exclusives, and will be available to xbox users by fall 2015. I believe they are sort of an "early access" to strikes that will come in the future (such as the undying mind coming with the hive dlc, its probably part of the vex dlc). And either way, I think bungie has treated you guys well enough for 10 some years (Halo?). So its only fair we get a little taste of exclusivity from bungie.
