We still don't have an official release date for Windows 10, but Microsoft maintains it's on track for release this summer. That's according to Joe Belfiore, its corporate vice president of operating systems, who spoke to media earlier today. You'll have to wait a bit longer to get Windows 10 on your phone and Xbox, though. Belfiore noted that bringing the new OS to PCs is Microsoft's main focus at the moment, but we'll likely see it hit those other platforms in the fall. He also included HoloLens among his list of other Windows 10 platforms, which could be a hint that we'll actually see it this fall. Or maybe that's just very wishful thinking.
