It just mean anyone who didn't pre-order the wayfarer edition can no longer make one for that specific edition. Normally special edition pre-orders are limited so the company stop allowing pre-orders for such editions a month or two before release since they reach their count or the manufacturer stops taking production orders.
TL;DR
If you already have the pre-order set up, don't worry they have your copy reserved.
If you only ordered the basic edition you can no longer upgrade unless someone cancels their special edition on pickup date and you luckily there to ask for the upgrade.
