StarCraftWire reports that Blizzard has started taking beta sign-ups for StarCraft II. Quoting: 'Interested parties must simply visit their Battle.net profile page, choose to opt-in for the beta, and re-submit their current system specs by way of a small downloadable piece of software.' Blizzard's Chris Sigaty said in an interview, 'As with previous betas for our real-time strategy games, the StarCraft II beta test will be multiplayer only, and players will have access to all three races — terrans, protoss, and zerg — and all of their units. We'll include a selection of multiplayer maps, but they won't necessarily include all of the maps that will be in the final version of the game. We're making some great progress on the single-player campaign, but we don't plan to do a public beta since we want to keep the story under wraps until the game's out
