User blog comment:The Milkman/Dragonborn DLC coming to PS3 and PC/@comment-3428817-20121204190841/@comment-4057437-20121206054415

Sales by platform as of 7/31/12, per Bethesda:

XBox 59%

PS3 27%

PC 14%

That the PC got content before PS3, even though their sales are less, is evidence that Bethesda isn't discriminating against the PS3 due to lower sales
