StarCraft II: Heart of the Swarm playable at MLG, Wings of Liberty on sale

StarCraft II Heart of the Swarm beta playable at MLG, Wings of Liberty on sale
The upcoming weekend is a big one for StarCraft fans: The United States Nationals of the StarCraft II World Championship is taking place at the MLG Spring Championship all weekend long. For those of you not interested the e-sports scene, there's another event coinciding with this one: The Heart of the Swarm press event is taking place this weekend, and an early build of the upcoming expansion is playable at demo stations on the MLG floor. Heart of the Swarm isn't officially in the beta phase yet, so this will be the first time players have an opportunity to see the expansion first-hand.

To celebrate both the Nationals and the Heart of the Swarm preview, Blizzard has put StarCraft II: Wings of Liberty on sale for the weekend. Blizzard has taken 33% off of the standard box price of $59.99, bringing the price down to $39.99.

Update: Check for further information on this weekend's events as well as a pair of video previews of Heart of the Swarm. You can also find the videos embedded below.
