Also got the same Q4 build window, it is just an estimate. Also this section for folks that haven’t received their build window:
Why have some received their estimated build window, while others have not?
For those who placed an initial reservation, we’re working our way through pre-orders based on the original reservation date. After this, for those who did not place a reservation, we’re taking the same approach, working through the pre-orders in chronological order. The number of pre-orders received has been phenomenal. This has taken us longer than expected, working with our Hambach scheduling teams, to allocate to production. However, we commit that this will be complete, with every customer who placed a pre-order up to the end of July receiving an estimated build window from us by the end of August. The team will continue to process and schedule any subsequent pre-orders just as quickly as possible. Apologies for the delay and thanks for your patience!
