BlizzCast 15 is now live! In this episode, we bring you in-depth coverage of the upcoming Cataclysm expansion and discuss everything from world creation to class changes to sound design.

The Cataclysm has wrought changes to many facets of Azeroth and the dungeons found across the world are no exception. As many of the zones throughout the world now have new level ranges, the dungeons within their borders have been adjusted to match, and the items that drop within those dungeons have had their stats changed accordingly.

We are applying a hotfix today to all level 1-60 dungeon quests for Kalimdor and Eastern Kingdoms dungeons which will significantly reduce the amount of experience they award.

The uneasy armistice between the Horde and Alliance is steadily cracking beneath the strain of Deathwing's devastating return and the Shattering of Azeroth, heralding a new era of bloody conflict.

The Cataclysmic launch of the new World of Warcraft expansion is just a week away! Make sure to put the date in your calendar, because attendees will be able to enjoy various activities and even pick up some great loot!

We’re pleased to announce that the two recently revealed in-game pets, Lil' Ragnaros and the Moonkin Hatchling, have now made their way to the Pet Store section of the online Blizzard Store.

The curious continue to flock to the Darkmoon Faire, hoping to catch a glimpse of their fate from the wise and (some say) frighteningly insightful Sayge. The combined efforts of the Horde and Alliance have brought them to the halfway point of the 'Your Fortune Awaits' campaign, unlocking a truly rare treasure. Sit back, relax, and enjoy this sneak peek of the Collector’s Edition DVD video, “The Making of Cataclysm.”

The Lich King's reign of terror was over. As if to affirm that a bright future would soon dawn on Azeroth, other joyful events occurred across the world. Archdruid Malfurion Stormrage was at last freed from his imprisonment by the shadowy Emerald Nightmare through the efforts of his love, High Priestess Tyrande Whisperwind, and her allies. Elsewhere, after years in exile, the highly intelligent gnomes and the fearless Darkspear trolls made gains toward reclaiming their respective homes in Gnomeregan and on the Echo Isles.

However, before he visits the inhabitants of Azeroth once more, he's offering some special gift baskets for the most creative adventurers.

With patch 4.0.3a now live, the stage has been set for the coming cataclysm. Deathwing has returned and Azeroth has been changed forever. Many of you have been anticipating this moment. You’ve posted, blogged, podcasted, and even tweeted about it. But, after Azeroth is torn asunder by the wrath of the corrupted Dragon Aspect, what will you do first?

In the frigid wastes of Northrend, the final battle against the merciless Lich King ended in victory for Azeroth's defenders. Upon returning home, veterans of the unforgiving conflict against the Scourge were showered with praise for their valiant sacrifices, while the honorable dead were mourned. Yet as hope flared anew in the wake of the Lich King's fall, Azeroth's native elemental spirits grew confused and erratic, setting off a series of deadly natural disasters. Horde and Alliance leaders scrambled for clues about the troubling state of the world, but nothing could have prepared them for what was to come.
