Blizzard Entertainment have announced a near worldwide (or as close as these things get) release date for Starcraft II: Wings of Liberty. The game will be released on July 27 smack in the middle of the summer.
Here is a quote from the press release:
"We've been looking forward to revisiting the StarCraft universe for many years, and we're excited that the time for that is almost here," said Mike Morhaime, CEO and cofounder of Blizzard Entertainment. "Thanks to our beta testers, we're making great progress on the final stages of development, and we'll be ready to welcome players all over the world to StarCraft II and the new Battle.net® in just a few months."
