Blizzard has decided to add a mysterious image to their website, likely to cause a bit of a buzz. Which I'd say has been extremely successful since they have pretty much everyone speculating on what it could mean.
Well the image was updated with a couple of squinty eyes, which could mean the Lich King has squinty eyes. Sure, that seems perfectly logical. Okay, so I'm not so good at the guessing games, but give me a riddle and well, I will still not have a clue.
It has been brought up that this could mean they will be announcing Diablo III. Although I would have guessed that a large announcement like that would have been saved for BlizzCon. Then again, you saw my guessing skills earlier in the article. The other theory before the eyes were added was possibly Starcraft III being released.
