Oculus revealed that they will have to temporarily suspend production on the Oculus Rift developer kits due to certain components no longer being manufactured. Without parts, they can't make more Rifts. Seems simple enough.

A post on the Oculus section on Reddit outlines what is happening and the current shipping situations.
Certain components used in the Oculus Rift developer kit are no longer being manufactured, meaning they are no longer available to us for production. As a result, we don't have the necessary materials to produce additional kits. We still have some stock available, but we're quickly running out. We are looking into alternate sources for the needed components, and we don't yet have a timeline for when additional units will be available. We'll be sure to keep everyone posted.

As we sell out of inventory in each region we plan to suspend sales in that region until we are able to deliver new orders. Currently we are only selling and shipping to the following countries:

- United States
- Canada
- Countries in the European Union
- Japan
- South Korea
- Australia
- Switzerland
- Norway

We never expected to sell so many development kits and VR only made this much progress with the community's support and enthusiasm. Even though we never wanted to sell out, it's a good problem to have -- Thank you!

The countries listed are the countries that, at this very moment, are still receiving shipments. It seems as though that list will be edited on Reddit as more and more countries stop receiving shipments.
