The Batch 2 Preorder will stay open till I've sold all the units coming in batch 2. If I don't sell out by the time they arrive, then it is just stock I hold and it is a typical sale. If Batch 2 preorders sell out, I'll get more on order from Germany. If it switches to inventory I hold, only once I'm close to being out of stock I'll order more, and I'll have to see when the container shipment schedule is so there could be a period without stock.
Perhaps this is more information than you wanted. Main things is Batch 2 Preorder is open. I've sold a couple already. And it is possible it could sell out before July 19th.
