By now, you've all heard about the masks. The dataminers over at MMO Champion found 2 new sets of Halloween masks in the PTR build: Male and Female Goblins, and Male and Female Worgen.
Female Worgen don't exist in the game, and the the textures are way more detailed than most current in-game models.
I'm going to join Boubouille and go on the record as saying that this is definitive evidence of Worgen as a new playable race.
1) All previous Halloween masks have been for playable races only.
2) The female worgen out of nowhere.
3) This is the big one: look really carefully at the textures. Sure, they look more detailed, right? Now go look at the new models for bear/cat. Notice how old textures are blocky, with solid colors, while the new textures take advantage of higher resolutions to add detail and shading that make the model look even more 3-D than it actually is? Creating depth even with a low polygon count? Detailed fur, rolls, ridges, etc.?
Now look at the detailed folds of skin around the mask's eyes. And the detail put into the fur, a quality only seen before on the new druid models. These textures reek of having a ton of work already put into them. It's just too much for something throwaway, especially considering that there's already 2 different male Worgen textures in the game. It took them this long to update druid forms, do you really expect me to believe that the art department could be bothered to put this much work into a throwaway mask? Not a chance.
I guess there's a chance it's a hoax, but it's so elaborate and unnecessary that I seriously doubt it.
The next edition of the PTR added masks for all of the races that have been speculated in the past as possible future playable races: Murlocs, Vykrul, Naga, etc. Even a never-before-seen female Ogre!
Except the female ogre isn't even a model-mapped texture, it's just a copy/paste of a drawing from the WoW tabletop RPG!
I think it's pretty clear that these are just meant as a misdirection to cover up the leak. Fully expect the Worgen/Goblin announcement next month. I'll be looking forward to playing both.
