"This week, we have started shipping the Vive Developer Editions. This first wave includes a wide range of developers from major movie studios, triple A developers, to small indie teams working on their first title. We will continue to ship to additional developers through the spring and summer.
In the box is a headset, 2 Lighthouse base stations, 2 wireless Steam VR controllers, various cables, instructions, and everything else needed to get started. This will allow developers to target the same system consumers will have in their homes later this year. "
