If you like the Nintendo Wii's 3D controller, you fall in love with the new Sony controller. It works with "sub millimeter" access and the controller itself has a cool glowing orb on its tip. The light-sabre whip and handwriting demos at E3 2009 are pretty impressive.The spraypaint demo reminds me of MacPaint circa 1984 and has the potential to revolutionize immersive gaming the way MacPaint revolutionized software UI.
How much does it threaten the Wii? How do you think that it stacks up against the new Project Natal 3D controller for Xbox?
