SKM: I think it's pretty clear that they're filling orders by SKU, not when the order was placed. And, for whatever reason, pink is at the bottom of the list of aluminum watches.
I've ordered a pink aluminum, too, and if I had to guess, I believe it will ship tomorrow or Monday.
Why they chose this way to fill orders is beyond me. It could have to do with adding more SKUs in one product than exist for all other Apple products. But it sort of defeats the purpose of getting up in the middle of the night to place your order, doesn't it?
I'd bet this is the last launch done this way.
