I was wrong, leak was true

Blizzard just officially announced the third World of Warcraft expansion, Cataclysm, and I was wrong doubting the leaks: They were completely true. My apologies. Best details can be found in the official Cataclysm FAQ, videos at the Cataclysm site. Main features are:

• Two New Playable Races: Adventure as one of two new races--the cursed worgen with the Alliance or the resourceful goblins with the Horde.
• Level Cap Increased to 85: Earn new abilities, tap into new talents, and progress through the path system, a new way for players to improve characters.
• Classic Zones Remade: Familiar zones across the original continents of Kalimdor and the Eastern Kingdoms have been altered forever and updated with new content, from the devastated Badlands to the broken Barrens, which has been sundered in two.
• New High-Level Zones: Explore newly opened parts of the world, including Uldum, Grim Batol, and the great Sunken City of Vashj'ir beneath the sea.
• More Raid Content than Ever Before: Enjoy more high-level raid content than previous expansions, with optional more challenging versions of all encounters.
• New Race and Class Combinations: Explore Azeroth as a gnome priest, blood elf warrior, or one of the other never-before-available race and class combinations.
• Guild Advancement: Progress as a guild to earn guild levels and guild achievements.
• New PvP Zone & Rated Battlegrounds: Take on PvP objectives and daily quests on Tol Barad Island, a new Wintergrasp-like zone, and wage war in all-new rated Battlegrounds.
• Archaeology: Master a new secondary profession to unearth valuable artifacts and earn unique rewards.
• Flying Mounts in Azeroth: Explore Kalimdor and the Eastern Kingdoms like never before.

The most interesting part in all of this is something that rarely, if ever, happens with an MMORPG expansion: The disappearance of old content. The old zones of Kalimdor and Eastern Kingdom will disappear. And that will happen for everyone, whether he bought the expansion or not: "When the Cataclysm occurs, it will occur for all players, whether they have purchased the expansion or not--you will no longer be to play in the original version of Kalimdor or the Eastern Kingdoms. However, certain features such as the new zones, new races, and new level cap will only be accessible to players who purchase the expansion." The original versions of the zones will disappear completely, and will be replaced by new versions, which are flight-enabled. Well, there is still quite a while until the Cataclysm happens, so you can still roll a couple of alts and explore the old world zones as they are right now. But when the expansion comes, the old content will be gone forever.

Oh, and there is no new hero class.
