"March 8, 2007 - Today Bethesda announced the price and release date for the latest expansion to its epic RPG landscape, The Elder Scrolls IV: The Shivering Isles. Players can download the expansion from Xbox Live the week of March 26 for 2400 Microsoft Points ($29.99)."
DC - 360 or PS3 owners I highly recommend you buy Oblivion. PS3 owners I don't know if you guys will get this expansion or not.
