SC2 ist noch weit von einer Beta-Version entfernt, demnach ist es eine Alpha, oder wie z.B. IGN und Gamespot sagen eine Pre-Alpha.
Singleplayer ist im uebrigen noch nicht spielbar:
"The panel answered questions on numerous topics, including Starcraft II's development history, which Pardo expained "started shortly after Warcraft III: The Frozen Throne" back in 2003. According to Pardo, the game is "very far along," and that the game is already playable in multiplayer with all three factions. When asked about the release date, Pardo gave the answer you may have come to expect from Blizzard: "The game will be released when it's ready." (Gamespot)

"Fans of the single-player storyline will have to wait for details, since the single-player's development is being held until the latter part of the overall cycle." (IGN)
Außerdem noch ein Zitat aus der offiziellen Praesentation auf dem WWI:
"Before we begin today I'd like to remind everyone this is only a demo! This is work in progress, we've got a lot of balance work ahead of us, nothing you're going to see today is final."
