Oculus says the new Rift headsets will be available on the Oculus website for preorder starting right about now, March 19, at 8AM Pacific. The headsets are estimated to ship in July of 2014. They'll be made available on a first-come, first-serve basis.P
The new DevKit still isn't the commercial version, and won't really be intended for the public. It's intended more for developers to start to learn how to make games work on a Rift. Of course, that doesn't mean that non-developers can't buy one...P
Each headset will cost $350, $50 more than the first DevKit cost. The extra $50 apparently covers the included camera that tracks your head movement. P
The DevKit 2 will run at 960x1080 resolution per eye, totaling out to 1920x1080, or 1080p between both eyes. It'll use a low-persistence OLED display with 6DOF positional tracking.P
Its refresh rates will be 75Hz, 72Hz, and 60HzP
It'll use a gyroscope, an accelerometer and a magnetometer for inertial tracking, and those sensors will update at 1000Hz.P
It'll weigh 440g without its cable.P
The headset is still called the Rift, and it will always be called the Rift. "Crystal Cove" was just a code-name for the DevKit 2, but isn't the name of the actual headset.P
Just like the Crystal Cove prototype, DevKit 2 will be able to track your head's movements via the included camera (which you mount on a fixed point in the room), so you can lean in closer to objects in the game-world to make your view grow closer. It goes a long way toward making the experience more immersive.P
The new headset looks a touch different than the Crystal Cove prototype - it's now solid black. It's also a more streamlined form-factor from the first Rift, and looks more like how we've come to expect VR headsets to look. P
Here are a couple of official photos, along with a shot of me using it yesterday
