Blizzard is announcing a game this Saturday in Europe. That's about all we know. They've been running these enigmatic splash pages for days now on their sites to drop misleading hints and drive everyone crazy. It could just be an announcement regarding World of Warcraft: Wrath of the Lich King, and that's probably the most likely possibility, but this looks like it might be something bigger. Another Starcraft announcement? We haven't gotten much in the past year. A Diablo 3 announcement? A Starcraft or Diablo MMO? A new property entirely? There are conspiracy theorists on the internet with irrefutable evidence that it's each one of those things.
Earlier tonight I almost decided to stay up tomorrow night until 4:00 am for the announcement. Almost. But I'm a recovering fanboy; I need to work to avoid these sorts of temptations.
