Microsoft is working hard on the successor to Windows 7, but the operating system is still in very early in development. The software giant hasn't even announced Windows 8 yet, though we do know it is coming sometime next year. All that we currently have to go on are rumors and leaks.
Leaked documents have mentioned support for USB 3.0, Bluetooth 3.0, facial recognition, stereoscopic 3D, instant on booting, HID, accelerometers, proximity sensors, hard drive encryption, GPS integration, as well as a strong focus on boot time, shut down time, and battery life. Rumors have included two user interfaces, a renewed push in PC gaming, and a sneak peek at CES 2011.
