Blizzard hasn’t confirmed that these are the official models, BB from MMOC is just pulling information from the PTR files and turning them into something we can see with our eyes nothing more. We know that the Horde and Alliance are getting different looking gear which is nice, I severely doubt though that the rogue and druid items will be so similar. If anything these pieces as well as the plate I posted about before could be NPC gear. The armor models however, are named Leather_ArgentHorde so you can come to your own conclusions. I’m sure in the next PTR build is going to let us play with the new dungeons and raids and we’ll see what the finished product is going to look like.
I really love the shoulders, they remind me of the Stormshroud shoulders (heh, first I leveled with ‘em, now I can buy an upgraded version of ‘em). But the head… well, nah, it looks like those green quality helmets you see in Northrend. Unlike Stormshroud shoulders the green helms are ugly.
