The way I understand it, the preorders fundthe making of the vinyl, so they can't even start making them til the preorders come through. And in this case, it's a complicated gatefold so it keeps getting delayed. Did you get the email from the owner talking about the extras people who ordered would get?
I have gotten the email and I work for a record label so I understand it. The preorder gives the label money up front but they can probably afford to undergo production before the preorder launches. I understand these things happen but the part I don't get is launching the preorder before you've figured out what jacket you're going to use, or before you've ordered the vinyl, or whatever.
