I'm going to remain skeptical - no offense to Pwnster and your contacts. If you had a verifiable track record from your sources, I'd be more willing to go with what you say, but I've been hearing "my freind at Blizzard told me" since the game was released. The raid guild I was in during vanilla had someone who had a friend who worked at Blizzard, who regaled us all with all the cool stuff coming in the expansion...which all turned out to be wrong. Turns out, the guys friend at Blizzard was telling him fake stuff to keep him off his back.

If it turns out to be true, cool. I don't really care either way. I don't have much interest in playing either Goblins or Worgen, but it'll be interesting to see how they do it.

If it turns out to not be true, cool. Let's see what Blizzard has up their sleeves.

Blizzard has been saying a lot lately, through official posts, blue comments, interviews, and everything else. They're dropping hints relentlessly. It's fun. Speculate away, nobody gets hurt, but don't get your hopes up too high.

It may be that they're just halloween masks. I don't know. I would love it if they really started playing with people's minds and seeded masks from Diablo III and Starcraft II characters and mobs- and let people argue and fight over what they mean for 6 months, all the while slipping the real stuff in quietly while everyone is raging over Halloween masks.
