It seems that the long awaited exclusive XBox 360 DLC might just be delayed right out of 2008 according to GameSpot.
In an article GameSpot tells us of a recent interview with Variety Dan Houser was asked when the DLC would be out. "I'm not sure. It's going well. But we don't know a date. We hope to be announcing that in the next few weeks. We're still figuring out a few things." He added that a major DLC release was "virgin territory, but at the same time, we feel very exposed because there's no case history."
On at least a promising note Microsoft itself stated that the additional content would be ready before December 31, so keep your fingers crossed!
