Microsoft (Nokia) is working on a successor to the Lumia 1020, codenamed McLaren, that will pair a massive PureView camera on the back of the smartphone with a bunch of other sensors to provide a new range of interactive gesture controls -- including Kinect-like finger movements above the screen, but also new 'gestures' like automatically enabling speakerphone if you place your phone on the table, or muting a call if you place it against your chest. The phone is destined to launch in November in the US, and it probably won't be a carrier exclusive.
