The beta test for the second piece of StarCraft 2 is coming to a close soon. Blizzard announced that StarCraft 2: Heart of the Swarm's beta will close on March 1, to pave the way for the official launch of the game. A private beta test will continue until the game goes live on March 12.
The announcement thanks the community for its support, and says it hopes for more feedback in the remaining three weeks. That should serve as your marching orders, not that it should be too difficult to convince anyone to play some more StarCraft.
This will be the second of three planned StarCraft 2 releases. The third game, Legacy of the Void, will focus on the Protoss race. The last we heard, it was tentatively planned to hit by the end of 2014.
