Microsoft's Mike Ybarra says that the next software update for the Xbox One for members of the Xbox Preview program is coming "soon". He did not offer a specific date.
Ybarra, who is the Director of Program Management at Microsoft's Xbox division, made the announcement on his Twitter account:
It's been a little while since members of the Xbox Preview program have downloaded a build to their Xbox One to try out. The last such release was back in March. It's expected that the next preview build will incorporate some features that will be released later to all Xbox One owners as part of the big Windows 10 Anniversary Update later this summer. That will include bringing the Windows Store to the Xbox One, among other features.
