Variety cites several sources in a report that claims Sony is preparing to announce a new motion controller for the PlayStation 3. The purported device uses a webcam and LEDs to achieve an accuracy of motion greater than that of the Wii.

Meanwhile, a tipster writing into Engadget says that Microsoft is readying a full-body motion sensing device. The rumor would see a high-tech sensor bar detecting a full range of movement without the use of an actual handheld controller.

As many motion controller rumors have certainly been proven false in the past, the Shack doctor recommends taking two grains of salt and calling us after the show.
