Bethesda has today announced that they are developing add-on content for Fallout: New Vegas. The first DLC pack for the game will be released just in time for Christmas on the Xbox Live Marketplace. It’s not currently known if/when it will be released on other platforms but going by Fallout 3’s DLC, it should only be a timed exclusive on the 360.

“We’re excited to continue the partnership between Bethesda and Microsoft, and build on the success of the game add-ons released for Fallout 3 on Xbox LIVE,” said Pete Hines, VP of Marketing and PR of Bethesda Softworks. “Fans will once again be able to continue their experience in the Fallout universe with the add-on packs planned for after the launch of the game.”

Fallout: New Vegas is out this week in all major territories on the PC, PS3 and 360.
