User blog comment:Saratje/PC release date explained - Skyrim: Dragonborn DLC/@comment-98.20.129.198-20130111085945

The DLC exclusivity is the price paid for developing a game on the xbox hardware. Apparently it's easier to design a (counsel) game on it than PS3. Keep in mind that they developed this as a counsel game first (despite it's PC history). The purpose being companies loose money on PC games because they are easier to pirate. Thats why developers design with a counsel first mindset, as there is less piracy in it. In the end it doesn't matter to me, wait time or not, I want the DLC, after 655 hours though, I'm still playing, and oddly enough finding new stuff.
