WoW - The Burning Crusade

The initial information about the expansion was announced on the first day of BlizzCon 2005. Some points of interest include:

• The Sword Of 1000 Truths from the South Park episode Make Love, Not Warcraft is likely to become available in The Burning Crusade.
• The Blood Elves will be the new Horde race. Their starting zone, Sunstrider Isle in Quel'Thalas, site of their capital of Silvermoon, is north of Eastern Plaguelands. Their classes will be: Rogue, Hunter, Mage, Priest, Warlock and Paladin.
• The Draenei will be the new Alliance race. Their starting zone, the Azuremyst Isles and their capital city Exodar are located off the northeastern coast of Kalimdor. Their classes will be: Warrior, Priest, Paladin, Mage, Shaman, and Hunter.
• The expansion pack will feature a new profession, jewelcrafting, which will allow players to create rings, necklaces and trinkets, as well as place mined gems into socketed items. Other professions will be augmented with recipes that include sockets for special jewels that will enhance items.
• The level cap will be raised from 60 to 70 with new abilities, spells, and talents for all characters and classes.
• A large new land will be available for exploration via the Dark Portal called Outland. This area is the remains of the ruined planet of Draenor.
• The talents for all classes have been revised and updated to allow for the new level cap of 70. You can read the changes here (Note: The talents that have been decided as of now are not final and may be subject to change before release)
• The landmass of Azeroth will be increased by 25% (This likely refers to the size of the gameworld, as opposed to land-area).
• A flying mount will be obtainable at level 70, after completing repeatable quests, which will be usable only in Outland. Some of the areas in Outland will only be reachable with this mount.
• The Alliance will get an armored Gryphon and the Horde will get an armored Wyvern. Both factions will be able to get the Nether Drake. In addition, Druid characters gain a flying form at level 68.
•  New dungeons include the Caverns of Time, the Hellfire Citadel, Karazhan Tower, the former sanctum of Medivh, and more.
• A new battleground called 'Eye of the Storm" located in Outland.
• Some content will be available to all players without the expansion, such as new talents and new items (such as items crafted with the Jewelcrafting profession). To level past level 60, play as the new races or to play in Outland, however, one will need the expansion. Other features that require the expansion will be forthcoming.[
• On July 21, 2006, it was announced that Blood Elves will be able to play as Paladins, which were previously unavailable to the Horde. Similarly, the Draenei will be able to play as Shaman, previously unavailable to the Alliance.
• New endgame instance raids are capped at 25 members (previous instances had a limit of 40 players).
• New dungeons will have scalable difficulty levels. What this means is that when you advance in levels, you'll be able to return to lower level dungeons and play them at increased difficulty, which will also yield better item drops. Blizzard is considering adding this feature to currently existing dungeons but has no plans to implement them yet.
• World of Warcraft: The Burning Crusade is currently undergoing a closed beta test in Korea. As with the World of Warcraft closed-beta test that occurred in Korea in 2004, participants can acquire beta keys from various fansites.
• Invitations for the United States Closed Beta were sent via email to those who had gone to BlizzCon on October 11, 2006, and the beta test is currently taking place.
• There was a conference for GameStop Store Managers from September 26, 2006 to September 30, 2006, in which store managers signed up for betas for the Burning Crusade. GameStop store managers were also high priority recipiants for the betas for World of Warcraft when it was first coming out.
