This isn't a major surprise, but Bloomberg is reporting that Microsoft is planning to finish up development on Windows 8 this summer, with the OS ready to ship on tablets and PCs in October. Bloomberg's sources of "people with knowledge of the schedule" line up with exactly what Microsoft hinted at back at CES — October will be three years after the launch of Windows 7, and director of Windows PR Janelle Poole noted that Microsoft wanted to keep on its "every three years" schedule. Close watchers of Microsoft have likely been targeted that month ever since Poole's comments, and now its becoming increasingly likely that October will bring the big unveiling. Hopefully we'll get the official word from Microsoft sooner than later.
