multiple sources tell us Sony shared details with partners. Those details include a resolution of 4000×2040 pixels (2000×2040 per eye), a lens separation adjustment dial, and gaze tracking capable of foveated rendering. A motor in the headset can be used by developers to give direct haptic feedback.
