The point is - there's enough phones produced by now and either already shipped or sitting in the warehouse waiting for their turn to fulfill all 2017 orders and a significant chunk (if not whole) of 2018 orders as well. Shipping happens chronologically and there are 2018 orders being processed already. Those left out are held due to lack of communication with customer to confirm their shipping address, international shipping procedures or other operational stuff, which is a drastically different situation than just a few months ago when not every 2017 order has even been produced yet (and to put things into perspective, a huge chunk of all orders was from 2017 as that's when the campaign to crowdfund its development happened).
