All bundles include an Oculus-certified PC and everything that comes along with the Rift - Headset, sensor, remote, an Xbox One controller, EVE: Valkyrie Founder’s Pack, and Lucky’s Tale.
You'll be able to pre-order the bundle from any of the three partners starting February 16th for shipping starting April 23rd. This means if you need a PC along with your Rift then you can get your hands on the Rift months before the current Rift pre-order date of July. If you missed out on the Rift pre-order and really really want one quick. This may be your best option.
Good luck to all.
