Onyxia Returns to WoW

The World of Warcraft Under Development Page outlines plans for a version 3.2.2 content patch that will feature the return of Onyxia (thanks Mike Martinez and 1Up). Word is:
This permanent update to Onyxia will convert the dungeon into a normal 10-player mode and a Heroic 25-player mode. We will be adding new items to Onyxia’s loot table that have the same model as some of the classic loot from this dungeon, like Tier 2 helms, with stats updated to match the current level of content. There will be a special new item too: a normal drake-sized 310% speed flying mount modeled after Onyxia herself called an Onyxia Broodling. We will also be updating the encounter mechanics to be more fitting for modern raiding, but we can guarantee players will get to experience the frightening horror of deep breaths once again.

Then for a limited time, after the 5-year anniversary event officially begins in November, anybody who logs in will receive an Onyxia Brood Whelpling pet.
