The purpose of a beta is to have a large number of users testing for bugs. Blizzard also used the beta to test StarCraft II's multiplayer balance. Blizzard expected to make changes once a week. In order to process the large volume of feedback, some information was collected by surveys.
The release of StarCraft II had been delayed to mid-2010 to give adequate time to prepare battle.net.
The beta itself opened February 17, 2010. In April 2010 the Macintosh version of the beta became available.
After the initial wave of invites, which included both those who opted-in and those who received beta keys, more players will be added when use drops or they need to test more users. Blizzard did not release the beta in different regions individually, as they set up beta-testing infrastructure in each region.
Blizzard traditionally offers 40,000 beta keys, but expectations for StarCraft II were larger. Blizzard aimed for 10,000 players online at one time during the beta.
The second and third waves were released on February 23 and March 6, 2010. Beta testers were given an additional key so they could invite a friend in March 2010.
On March 25, 2010, the beta database was wiped, removing characters, friends lists, profiles and ladder/league placements. The process was repeated on April 22nd and again in June.
1) The first wave will include both opt-ins and those who have/won codes.
2) If you are interested in beta, you can still opt-in, and potentially be invited into the first wave. Karune. 2010-02-11. Beta selection questions(for clarification)Battle.net StarCraft II General Discussion Forum. Accessed 2010-02-11.
↑We previously announced that the first phase of the StarCraft II beta test would be coming to a close in all regions on Monday, May 31. In order to prepare for the final phase of beta testing, we plan to extend the current phase in all regions until Monday, June 7. After this date, the beta test will be unavailable for several weeks while we make some hardware and software configuration changes for the final phase of the beta test and the release of the game. We plan to bring the beta test back online for a couple of weeks prior to the game’s launch to complete our testing. We’ll have more details to share about when this final phase will begin at a later date.
We’d like to thank all of our beta-test participants for your enthusiasm, dedication, and valuable feedback during the beta test, and we look forward to hearing more of your thoughts on the StarCraft II beta test as the game’s July 27 launch approaches.

↑ 26.026.1As you would expect, a lot of people opted in for beta. Additionally, there will be a large capacity for players on beta. During BlizzCon in 08, approximately 20k visitors got beta keys to Blizzard games, which could be used for StarCraft II.
We want to get as many people who have promised keys in as early as we can. Nonetheless, we will also have a large percentage in based on computer specs, to adequately test the game on several hardware types as well.
I would wait until beta starts to see if you've gotten a key in the first wave if you are only buying a computer for beta. Though don't forget - betas lead to game launches :) Karune. 2010-02-11. Blue Please Answer (not beta date related). StarCraft II General Discussion Forum. Accessed 2010-02-11.
↑It doesn't matter at what point you opted in. Those dates will not be considered when the names are taken out of the pool of people that opted in. So someone opting in today will have the same chance of getting into the beta. Xordiah. 2010-02-11. Mac, to be found in the closed beta as well?
