In addition to the launch and pricing information, Sony also revealed the PlayStation 3's new "redesigned" controller. The company showcased a boomerang-shaped controller at last year's E3, but the final version sports a look very similar to the existing PlayStation 2 DualShock gamepad. Despite the similarity, the new PS3 controller features an internal gyroscope that allows players to control game movement with six degrees of freedom by simply tilting the controller. SCE Worldwide Studios President Phil Harrison was quick to add that the gamepad also did not need external sensors to function—a requirement for the Nintendo Wii's motion-sensing controller. The PlayStation 3 can't detect the input device's position in a 3D space, though, unlike the Wii.
