Towards a spring 2015 release
The commercial launch for Windows 9 (code name: Threshold) could take place in April 2015. Microsoft is believed to be planning to make all of its products (PCs, smartphones, tablets, games consoles...) migrate towards a single system.
Characterized by its completely redesigned interface and its compatibility with touchscreen devices, Windows 8 was released on October 26, 2012. A few days earlier, Microsoft CEO Bill Gates himself had hinted at that Windows and Windows Phone should one day converge towards a single platform.
