World of Warcraft: The Burning Crusade Previews

Both GameSpot and IGN PC have whipped up hands-on previews of Blizzard's newly announced World of Warcraft: The Burning Legion expansion pack. A snip from GameSpot's article:
If you've played World of Warcraft before, then you won't be very surprised at the sorts of starting quests you'll be asked to do, which include killing X number of Y creatures, and possibly returning Z number of items to quest givers. The first one sent us over to a nearby large green crystal, where we had to clear the area of eight ghostly, eel-like creatures. We were then asked to clear out the surrounding area of lynxes and collect some of their collars. Later on, we were asked to explore a mystical tower to the west of our starting town and clear it of wraiths that had overrun the winding ramps and platforms of the structure. Unfortunately, just as we were about to turn in the quest items and get more information on why the tower had been overrun by evil spirits, our time on the station ran out.

And a snip from IGN PC's article:
Burning Crusade also raises the level cap to 70, and I'm pleased to report that we won't just get upgrades of previous skills (Fireball 6, Greater Heal 9, and the like), but they wouldn't get into specifics just yet. But they did say that there would be new Talents as well, and a re-working of the trees to adjust some abilities that either aren't that useful or are situated in the wrong tier. (Talent restructuring is still an ongoing process for the live game -- they haven't put that on the back burner). You can also get a Nether Dragon flying mount at level 70, after a challenging and time-consuming quest, although you can only use it in the Outlands (formerly known as Draenor, the broken planet on the other side of the Dark Portal in the Blasted Lands). It won't move as fast as the existing airborne transportation, and you can't attack while mounted (nor can you on any other mounts), but the flying capability will allow you to reach some content that's impossible to access on foot.
