Major Nelson has just announced sign ups for an upcoming Xbox 360 beta dashboard update are now open. The new update will improve overall performance and introduce the local currency system which will replace Microsoft Points.
You can find more details in the quote from Major Nelson's blog below.
Unlike our previous beta programs, sign up is now accessed directly through your Xbox 360 console to streamline the experience. Space is 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) for confidentiality reasons.
For more details on the beta, we will have a Beta FAQ that posted here later today.
Our open public betas allow you to help make Xbox even better.
We appreciate your feedback and thank you for participating!
* Xbox Live members in any of our 41 Xbox Live-enabled markets will be able to participate in the public beta for Xbox 360. Please note that members in Japan will have an opportunity to join at a later date.
I'll update this post when we open it for Japan, and additional information about the program as it progresses
