We've had two prerelease versions on our teardown table, so we're excited to see what tweaks this Rift has in store. Here's the scoop so far:

Two OLED displays with a combined resolution of 2160 x 1200

90 Hz refresh rate

Accelerometer, gyroscope, and magnetometer

360-degree headset tracking via Constellation IR camera

Horizontal field of view greater than 100º

The Rift's custom VR motion controllers, known as Oculus Touch, will be ready later this year. Perhaps we'll tear them down at that time, if we're not hopelessly lost on the Grid.
