If you were looking to grab the Artorias of the Abyss content for Dark Souls without having to rebuy the Prepare to Die Edition of the game, that option is now available for Xbox 360 and PlayStation 3 players. It's downloadable as of today on Xbox Live and PlayStation Network.
At $14.99 / 1200 Microsoft Points, those of you with a time-versus-money-spent mentality might have a tough call to make. At any rate, the quality of the experience was, for me, easily worth it. To sum it up briefly: a couple of great boss fights, the creepy setting of Oolacile, an unexpected summon, and added PvP functionality are what's in store.
