OnePlus has announced that the reservation system for the OnePlus 2 will close on October 22. After this date it will no longer be possible for anyone to reserve a unit for themselves while the company attempts to honor reservations already placed. The plan is to roll out as many units as possible without overshooting and letting consumers down.
Those who have already reserved (or will do so within the week) will eventually receive their invites, depending on where they happen to be located in the queue. And these positions will be locked from October 22 too, so where you end up next week will be where you remain until you're finally able to make the purchase.
Not all hope is lost for those who miss out, however. OnePlus will still pump out shareable invites to those who purchase the smartphone and contests will also run on social media to hand out a few invitations. See the official announcement for more details.
