Starcraft2 release date

I'm not sure what you are talking about because Starcraft 2 is released already. But it was released July 27, 2010. This is only counting Wings of Liberty because no one knows when Heart of the Swarm or Legacy of the Void will come out (my guess is that Heart of the Swarm will come out 2012-1013 and Legacy of the Void will come out in 2014-1015).
