Variety.com is going out on a little limb today, reporting that Sony’s much rumoured motion sensing controller is not only ‘real’ but is also due to be shown at E3 next month. A source has told Variety that a working prototype has been available for months, and largely fits what was in the original patent – the controller apparently uses LEDs and a tiny webcam to track movement. So far, Sony has declined to comment so its best to consider this as a rumor for now (at least until E3 anyway).
