User blog comment:Sgt. S.S./Why PS3 users need to calm down over the DLCs/@comment-3202167-20130113142359/@comment-3492791-20130115204102

Microsoft gave Bethesda (or more likely Zenimax) a big bag of money and Bethesda agreed to release [a number] of DLCs with 30 day exclusivity for the Xbox 360. It is Bethesda's right as the creator of content to distribute it in any way they see fit. They accepted the money and terms offered by Microsoft because both parties saw a profit in it. Because both companies are businesses who's purpose is to make money.

After the 30 days agreed upon on the terms of the deal have passes, Microsoft is not responsible, or has any influence, over content being available on any other media. That fault falls to Bethesda.
