Official previews for more of Tier 10 is out now. So far things are looking good. We'll see how they look in the game whenever 3.3 hits. Blizzard's armor preview
has a bunch of official T10 sets up. Go take a look, they are looking great.
Patch 3.3, the next major update for World of Warcraft: Wrath of the Lich King, will add another tier of powerful high-level armor sets to the game. You can click on the thumbnails above to catch a sneak peek for each set, and you can also click the link below the image to download a high-res version of each image.
More sets will be released as testing on the PTR continues; stay tuned!
