Apparently, a few sources jumped the gun when they stated the upcoming Fable II DLC would be out by December 12. A Lionhead rep has clarified this error, confirming a mid-December date instead.
The Knothole Island DLC will be available on XBL on December 22. A co-op patch will allow players without the DLC to play alongside those who purchased it. The new content will remain off limits until both players have the DLC, however.
In addition to the new story and explorable region, Lionhead is including some "festive" gifts with either the downloadable bundle or the free patch, including Knight's Boots, Assassin's Gloves, Weight Loss Potion (guess you don't have to keep eating Celery), collectible books and more.
More details can be found on our previous article regarding the DLC, first posted in November. There had been no solid release date at the time.
