Seems Diablo III beta might be closer than the expected September window. Bashiok is urging fans to double-check in their Battle.net account that all three games are selected in the beta settings section. Once you are certain the opt-in for Diablo III beta is enabled, you might be among the fortunate to be randomly selected.
If you are not selected, there are other options. Blizzard will send several invite waves throughout beta as they fine tune the servers to support large amount of players.
More options? Shh ... fansites and gaming networks might get a certain amount of beta keys to giveaway. Be eye-sharp for those. I will update in the news whenever I find one of those contests so you go participate.
The beta test approaches! We’ve just updated our System Check program and would like everyone to update their Battle.net Beta Profile information by running the new one. You should do this regardless of whether there have been hardware changes made to your system.
You can run the new System Check by visiting the Beta Profile settings of your Battle.net account:
I don’t have a Beta Profile If you haven’t yet created a Beta Profile on your Battle.net account you’ll be presented with two download options, PC and Mac, for our System Check program. Running the program will present you with the Beta Test Opt-In Agreement, and once you agree to that it will immediately query basic computer specification information such as your type of video card, processor, and RAM. Clicking the Send button will then upload the shown information to your account.
On your Beta Profile page, you’ll want to ensure you at least have “Diablo Universe” checked for future testing, if not StarCraft and Warcraft as well. That’s it! You’re now eligible for future beta test opportunities.
I have a Beta Profile If you’ve previously uploaded your system info you should use the links to download the new System Check program for PC or Mac and update your system info. Run the program, read through the Beta Test Opt-In Agreement that appears, and once you agree to that the program will immediately query your basic computer specification information. Click Send and the program will automatically update your profile with your system specifications. You’ll remain opted in for whichever beta tests you’ve previously selected, and you can change these selections on your Beta Profile page at any time.
Having current system specifications and checking the franchise boxes to express interest in beta testing our future products does not guarantee your entry into the beta test. We will grant a very limited number of people entry from the entire pool of those interested, based on their system specifications and other factors. While having an official Battle.net Beta Profile is one way to potentially get in, we’ll have information on other ways to increase your chances as we draw closer to the beta test. -- Source
