World of Warcraft: The Burning Crusade Previews

Both ActionTrip and PC Gameworld are offering up their own previews of Blizzard's recently announced World of Warcraft: The Burning Crusade expansion. A snip from ActionTrip's article:
A bunch more of great new content is planned for the expansion pack. For starters, a myriad of new dungeons - lots of them in the Outland and of course, some back in the old areas. Players can also get new transportation in Outland; a flying Nether Dragon mount, which you'll acquire after finishing a grueling quest at lvl 70. You'll only be able to mount your dragon in the Outland (they have no laws against such practices there -Mo), and as ever, you won't be able to fight while on it. Another very interesting extra to the game will be the Jewelcrafting profession, and the addition of Diablo-esque socketed items. Needless to say, this change will greatly enhance the customizability of the equipment, letting the players busy themselves even more with the best possible stats they can squeeze out of their precious gear.

And a snip from PC Gameworld's article:
If there have been some questions raised about the expansion, it mainly concerns the addition of Blood Elves. These Elves have been added to the side of the Horde, as opposed to the usual Alliance, and their presence means that the Horde will finally have some '˜pretty' villains (usually they are ugly). This could either be viewed as a mistake or as a bold attempt to give the game some complexity. It depends on how tolerant you are to change, really - it is possible that mixing things up could produce some nice results.
