Rather than highlighting new Surface hardware as anticipated, Microsoft's rumored spring event might instead be focused on Windows 10 Cloud Edition. As reported by ZDNet's Mary Jo Foley and Cassim Ketfi, the spring event is internally going by the codename "Bespin". If you're at all familiar with the Star Wars universe, Bespin is the location of Cloud City, which could offer a hint at the event's focus.

Windows 10 Cloud might be the focus of Microsoft's rumored spring event

Further, Foley notes that we're likely to see invitations for the event, which is expected to take place in early May, go out within the "next few days," likely providing further hints at what to expect.

Windows 10 Cloud hands on: An edition of Windows for Store apps only

Aside from the reference in its name, Windows 10 Cloud doesn't have much to do with the cloud at all. Rather, the OS is more akin to the now-defunct Windows RT in that it will only run Unified Windows Platform (UWP) apps from the Windows Store. With its more simplified platform, speculation is that Microsoft may be looking to take on Chromebooks with low-cost devices that only run Windows Store apps. Should you need access to apps outside of the store, signs point to a path within the system to upgrade to Windows 10 Pro for a fee.

Other than Windows 10 Cloud, it's looking less and less likely that we'll see any major Surface announcements soon. The rumor mill has already pointed to the absence of a Surface Book 2 debut this spring, and it's also looking likely that any Surface Pro 5 refresh would be more iterative than revolutionary.

In any case, we should find out relatively soon what Microsoft may have up its sleeve.
