According to the company site pre-orders for the Rift will open on Oculus.com at 8am Pacific Time on January 6.  The site is promising more details about how to order your Rift tomorrow  when pre-orders go live.

Each Rift comes bundled with Lucky’s Tale by Playful, and we’re also including CCP’s EVE: Valkyrie for free with every pre-order!

"This is going to be an exciting week for VR, so Oculus founder Palmer Luckey will be answering all your questions during a Reddit AMA this Wednesday, January 6 at 6pm Pacific Time. We look forward to hearing from you," the site says..

It is pre-order so we don't know when the new machines will be shipped or how much they will cost. We expect to be told tomorrow.
