During a Press conference, the CEO said the Beta will come out sometime this summer. He then said in an E3 webcast that the first installment will be released "late 2009" (There will be 3 parts of SC2, each being the races, they will be released terran first, zerg, then toss. Each will run you at $50, yea, the game will cost $150 minimum. However, If you only get the the game no expansions, you WILL still be able to play all three races in multiplayer)
Its only a matter of time now.....
