Microsoft has opened up its public beta for the 2013 Xbox Live Update for Xbox 360 Public Beta. The update will improve overall performance and the ability to conduct transactions with local currency, as Microsoft Points will be retired later this year. It has been that rumored smaller live tiles will also come to the interface and the final update will come in late August.
Unlike our previous beta programs, sign up is now accessed directly through your Xbox 360 console. Space will be limited, so once the spots are filled the beta will be closed to the public. To join, look for the Xbox Beta Program tile on the home hub of the Xbox Dashboard.
You will be required to agree to a non-disclosure agreement (NDA), but I’ve rarely seen these followed.
If you are an Xbox Member in Japan you will not be able to sign up at this time.
