Giving the development kits away for free could help Valve and HTC encourage developers who are already making games for the Oculus Rift and Sony's Project Morpheus develop games for Vive as well, which Valve said will be out by the end of the year. Oculus, by comparison, currently charges $350 for development kits, while the Samsung Gear VR Innovator Edition (which is powered by Oculus and a Galaxy Note 4 smartphone) is already for sale at Best Buy for $199.
