Currently, those who are enrolled in the Xbox preview program and have historically submitted the most feedback are the lucky ones to snag the New Xbox One Experience (NXOE) Preview update. Microsoft wants to get feedback from an initial group of testers, then roll out the update to larger groups for additional feedback over time.
This is changing over the course of the next few days. According to Microsoft’s Partner Director of Program Management, Mike Ybarra, the preview will be rolling out in the next few days to everyone who signed up. You must be in the Xbox Preview program in order to opt into the NXOE preview, and your invite should be arriving in the next few days.
Microsoft is sending invites to the update to preview members via an Xbox Live message. Once an invite is received, you can launch the Xbox Preview Dashboard and select the registration option. From there, you can opt-in by selecting “Preview – New Xbox One Experience.”
@FameEnt2k We hope in the next few days to everyone who signed up.
