According to The Verge, “sources familiar with Microsoft’s plans” claim that the company is “tentatively” planning a press event for 30th September, at which Windows 9 will get its big unveiling.
CROSSING THE THRESHOLD
The new version of Windows is currently codenamed “Threshold” – it might not actually be called “Windows 9” at all – and will add a number of new features and UI changes: Microsoft’s Cortana personal assistant will be included, the Charms bar will be going bye-bye and a new miniature Start Menu is set to be debuted.
It’s been rumoured in the past that a preview version of Threshold would be made available to developers as early as October of this year, and that ties neatly in with a potential late September announcement. Stay tuned for updates in the coming weeks.
