As sent out today in Microsoft’s press email
As we gear up to bring you the New Xbox Experience, Xbox LIVE and the Xbox LIVE page on Xbox.com will be down for 24 hours, beginning on September 29, 2008 from 12:01 AM PST until 11:59 PM PST. During this time you will not be able to access Xbox LIVE. For more information about the New Xbox Experience, please visit www.gamerscoreblog.com or www.majornelson.com.
Anyone think we will get anything new when it comes back?
