Next patch guess

I have a feeling blizzard is throwing off us for blizzcon, (which I'm not going to :/ failopse!) with the the goblin and worgen masks, or at least half. It would make perfect sense if that was try because then the mael storm would be sitting in our laps. But (I'm not a lore nerd) all I really know about the worgens is that they are from another dimension which seems a bit like emerald dream but not much. So much prediction is that we will probably see goblins next patch but something else besides worgens.
