We saw a Microsoft patent on a Wiimote-like device, and now rumors say that Sony too has a similar device in the works.This isn't surprising, given how dominant Nintendo's Wii has proved to be in this hardware generation.
However, many gaming-geeks continue to lament the move away from plain old button-pressing. What is exciting is the prospect that all three companies may incorporate Johnny Lee-style head-tracking into the next console generation, which achieves a convincing 3D illusion on a regular vid-screen, leaving us just a few steps away from true positional 3D.
Both the Microsoft and Sony patents incorporate a camera looking at the user, a required setup for achieving positional head-tracking.
