As we inch closer to the first big reveal of Windows Threshold -- expected on September 30 in the form of an enterprise technical preview -- rumors are flying about the role of "the cloud" in the coming Windows release.
No doubt there will be OneDrive integration with Windows Threshold, the next version of Windows which (in spite of a Microsoft China "leak") may or may not be called Windows 9 in the spring of 2015 when it's targeted to be available. There will be Skype integration. I wouldn't be surprised to see Outlook.com figuring in there somehow. And there has been talk about some kind of new backup
capabilities, likely coming from the Azure side of the house....
But there have also been not-so-secret mentions of something called "Windows as a Service" that Microsoft watchers are linking to Windows Threshold. I've seen a few speculate that this means there is something in the works akin to an Office 365-type subscription pricing/service for Threshold.
