World of Warcraft Icecrown Citadel Preview

Blizzard's official World of Warcraft website has been updated with a preview of Icecrown Citadel: The Frozen Halls, a new five-man dungeon being introduced in the upcoming v3.3 content patch.
Icecrown Citadel will feature a massive five-player dungeon sprawling across three wings of the citadel's foundation. While the Lich King's attention is focused on the Argent Crusade and the Knights of the Ebon Blade ripping through the front gates, players will be tested as they assist Jaina Proudmoore (Alliance) and Sylvanas Windrunner (Horde) in infiltrating the citadel through an alternate entrance.

An epic quest line will present adventurers with the task of weakening Icecrown Citadel's forces, requiring that players defeat the challenges in each dungeon wing before venturing into the next one. Normal and Heroic versions of the dungeon will be accessible to players, although each wing will be considered a separate instance; therefore, on Heroic difficulty, each wing will have its own separate lockout timer. All-new rewards -- including item level 219 (normal) and level 232 (Heroic) loot -- will be offered to those who destroy some of the Lich King's most formidable allies.
