It seems that the Xbox LIVE Public Preview for the new dashboard will soon be going live as Microsoft has posted up a link on its connect.microsoft.com website; the website it usually uses to ask people to sign up to test out new dashboard updates.
Currently you can’t request a place on the beta, however it does say, “We are now accepting new users into the Xbox LIVE Update Public Preview – Fall 2011 session. If you clicked on the link from Major Nelson and have not registered yet, please make sure you sign in with a Windows Live ID in the upper right hand corner. You only need to register one time.”
Maybe we are just waiting on Major Nelson to get the post up on his blog, either way, keep an eye on this site if you want to sign up for an early look at the update.
