Order guide can be downloaded here (when available): https://blueovalforums.com/forums/index.php?/files/categories/Traditionally the website is updated 1-3 months AFTER the order banks open, not before. However, last year Ford updated the website around the same day the order banks opened. (And for those who remember it was extremely buggy.)
Your best bet is to reach out to a dealer a few days before the order banks open and ask for an Order Guide. The Order Guide will also likely be posted on this forum, so you can always come back around mid-August to see if it has been posted.
