BioWare teased a Dragon Age: Origins announcement yesterday and today they delivered. They revealed that a new downloadable episode will be released this holiday season.

The episode is called Return to Ostagar. The following features are mentioned on the DA:O add-ons website:

• A return to the battlefields of Ostagar, now thick with darkspawn encamped amidst the snow
• An opportunity to reclaim the lost arms and armor of a king
• A second chance to add Dog to your party

Ostagar will cost $5 (400 MS Points). To access the new content, you'll have to be a few hours into the game. As soon as you visit the village of Lothering, you should be good to go.
