Though it hasn't had an official preview yet, the tier 12 set for warriors is available in the patch 4.2
PTR files, and Wowhead
dug it up along with recolors for all of the other already-previewed tier 12 sets
. You can even model them on the race and gender of your choice with the 3-D model viewer. If you can't see from the above picture, yes, those are molten giant heads on your shoulders, which is fitting, given the set's name of "Molten Giant Battlegear."
When you're done modeling your set on your character of choice, be sure to check out the preliminary tier 12 set bonuses
to go along with it.
