World of Warcraft: The Burning Crusade Preview

GamePro has put together their own preview of World of Warcraft: The Burning Crusade, based on what was revealed at Blizzard's BlizzCon event. A taste:
How else will the World of Warcraft, as you know it, change? Not only will the level cap increase to 70, but Blizzard will also add new talents to the talent trees, potentially meaning there will be an uber 41-point talent ability. Although no hero classes or new classes will be introduced, Blizzard promises to add new spells--not only to levels 60 and up, but starting from the 40s. "Currently we're not planning any new classes," says Kaplan. The company is focused to, "Develop existing classes post-40." In short, expect raid strategies to change--Kaplan says there will be "new gameplay mechanics for every class."
