Over a month ago, I was told this (regional centers/Hubs) by a Slate Agent via the chat. I had asked about delivery at the Warsaw plant and she said no, they will be shipped to a delivery center (I can't tell you where or how many yet...we're working it...soon) and you can get your Slate there; OR, for a small fee, we'll delivery it to you / your house. When I asked about the "small fee", she said hundreds not thousands.@kvermeer has deduced a concept of regional centers (he calls them Hubs) based on the early delivery windows. He may just be right!
