Oculus has already started taking pre-orders for the Rift Developer Kit. The cost is $300 and the orders are expected to ship January 2013.

Previously, the early development kits were only available to those who contributed to the device’s Kickstarter fund. The unique VR visors already have the support of the free-to-play game Hawken and id’s enhanced re-release Doom 3: BFG Edition.
