World of Warcraft: The Burning Crusade Preview

The guys at Eurogamer bring us the latest preview of Blizzard's newly revealed World of Warcraft: The Burning Crusade expansion pack, based on what was demonstrated at BlizzCon. It sounds like they have a couple of reservations, though:
The second reservation many have is that it's a shame that the pack isn't going to add a true new character class. "The primary reason not to do it is so we can focus more on developing the character classes we already have," Tom explains, when quizzed on the topic, "As we go from 60 to 70 we can add abilities, extend all the talent trees and work on the concept of heroes. Even though things are going to evolve, it's still very important for us to dedicate enough time to do heroes that feels really good and captures the spirit of the heroes in Warcraft III, and we don't short-change it by focusing too much on new character classes." It's worth noting, in passing, that its current vision of hero prestige classes is something that's more accessible than just the high-level elites. There's another issue which prevents the addition of new issues of a priority too. "There are players out there who haven't really exhausted all the character classes we have now," Tom argues, "How many people do you know who've maxed out every single character class? There might be a hardcore few who feel as if they've worn them all out, but for the vast majority of players, there's lots to do."
