With Mists of Pandaria approaching, the PvP sets of the upcoming Season 12 have been added to the game only recently.
The items have three tiers, hence three types of recolors of the same itemset.
DREADFUL itemlevel 464, purchased with Honor points.
MALEVOLENT itemlevel 483 purchased with Conquest points.
ELITE itemlevel 502 (?) they have the same stats as the Malevolent tier at the moment.
Note that the screenshots are rather low resolution so that the article isn't lagy and/or doesn't consume too much bandwidth.
