As a sneak peak (and in order of appearance on the PTR [Public Test Realms]), Blizzard has published pictures of the upcomging Tier 10 armor.
WoW warrior Tier10 armor
Tier armor is, if you’re not a WoW raider, a set of armor that is obtained by running raid instances and hoping “your” armor drops. Since the armor has shared drop rates between classes, it is a long and tedious process to get a full set, which offers very good stats bonuses and gives you additional bonuses for owning parts of or the full set.
Tier 10, purportedly the most advanced armor set in the game, will be introduced with patch 3.3 and drop from the Icecrown Citadel. It looks kinda cool (this is the warrior armor, click this link for more previews).
