All I can say (as a PS4 user) is that I think it's unfair, and this is taking a number of steps too far. In the core game, the one exclusive strike (Dust Palace) represented a relatively small amount of content in the total game, so making it PS only wasn't that big a deal. For this DLC, which has 3 story missions (will finish all 3 in about 30 minutes and never touch them again other than Daily Heroics), 1 or 2 strikes depending on your platform, and 1 raid, that exclusive strike is a major piece of content. Imagine if 3 or 4 of the original game's strikes were PS exclusive. Making it exclusive and asking Xbox users to pay the same price is unfair - and worse than that, whatever effect it might have on short term profits for Bungie/Activision, you can be sure in the longer term it is going to generate a lot of negative sentiment towards both companies and this game - at a time where there is already a great deal of negative sentiment in all corners of the internet for a multitude of other reasons, it's a large risk, and one with virtually no pay-off to Bungie at all, other than whatever amount of money Sony paid to Activision for the content. Especially considering the next CoD (arguably the most hyped in years) is going to be out very soon. I really want this game (and franchise) to survive, and to improve. Really hope it doesn't become the next Halo 4.
