And I have a keyboard being shipped to me from a US warehouse, but my Studio display is coming from China. You can see the difference in UPS My Choice.
The fact that something is true sometimes does not mean it’s true all the time. Keeping product in a warehouse for months is wasteful and inefficient.
I don't think we disagree - I even said most pre-order product will come direct from China. I'm just pointing out it's highly likely that some Studio Macs and Displays will come from the regional warehouses too and those may not have tracking info until tomorrow. Also, Apple does aim to keep a 4-week inventory in warehouses -- obviously not always possible the last couple of years. Apple execs, usually TC, often reiterate this inventory goal when asked about inventory levels during earnings calls.
