It seems Microsoft has managed to land more timed exclusive DLC for the Xbox 360. They revealed today that Xbox Live will be receiving Elder Scrolls V: Skyrim before the PC or PS3.
The timed exclusivity will apply to the first two downloadable add-ons for Skyrim. This window of exclusivity will last at least 30 days. After that time, Bethesda will be free to release the content on other platforms.
Microsoft has taken a similar approach with other high-profile multiplatform games. They've got a multi-year agreement with Activision for Call of Duty's DLC. Like the Skyrim DLC, the add-ons for the past two COD games were released on Xbox Live a month before anywhere else.
Fallout: New Vegas's first downloadable content pack, Dead Money, was a 360 exclusive as well. It took two months for that content to hit the PS3 and PC. Maybe the agreement between Microsoft and Bethesda on New Vegas specified two months. Still, it's worth pointing out that just because Bethesda can release Skyrim content on the PS3 and PC a month after the Xbox 360, you might have to wait longer than that.
Elder Scrolls V: Skyrim takes place two hundred years after Elder Scrolls IV: Oblivion. Alduin, the Nordic god of destruction, is prophecied to return and destroy Tamriel along with an army of black dragons. The player takes on the role of the last Dragonborn, a dragon hunter. It's up to him to stop Alduin and his forces. Skyrim will be released on November 11th.
Oh, and not to brag or anything, but I managed to get through an entire article about Elder Scrolls DLC without making a horse armor joke. That feels kinda noteworthy.
