World of Warcraft: The Burning Crusade Previews

Both GameSpot and Voodoo Extreme have conjured up new hand-on previews of Blizzard's upcoming World of Warcraft: The Burning Crusade expansion pack. A snip from GameSpot's article:
The Exodar is almost certainly the largest city in Azeroth, and even as a Tauren-sized draenei, the scale of it can feel quite overwhelming the first time you visit. The city boasts all of the usual districts, along with two banks and two auction houses--which will hopefully cut down on lag in those locations should the new city become a popular place for players to hang out. The Exodar is a city that feels like a combination of the dwarves' Ironforge and the undead's Undercity--the whole city is enclosed within one giant structure (the ship's hull) and has a lot of wide open spaces that are a little disconcerting at this point, but will no doubt feel quite different when populated with players.

And a snip from Voodoo Extreme's article:
Let's face it...two new races are all fine and dandy, but the meat of the expansion is the new Level 60-plus content, which is being introduced in the form of The Outlands. Outlands will include seven new zones, and of course, each zone has its own theme, instances, towns, quests and World PvP objectives and is targeted to a specific level range. Since the expansion is raising the level cap from 60 to 70, the zones ramp up in difficulty starting from 60.

A large batch of new screenshots complement both previews, as well.
