It seems Samsung is following the idea of Oculus and releasing their equivalent of the Oculus Rift Development Kit. Samsung calls it the Samsung Gear VR Innovators Edition. It is currently available directly from Samsung for pre-order for $199.
The site does not currently say when it will ship, however at their developer conference they said "sometime early December"
Samsung will also package the Gear VR Innovators Edition with a Bluetooth gamepad for $249.
Remember folks this device (unlike the DK2) also requires you to own the Note 4 that provides the Quad HD 2560x1440 resolution.
