Yeah, I think so it will happen. But the status change must be this week or beginning of next week to preparation to shipIt's been the same with the M1 MacBook Pro release last year. Pre-ordered within minutes after shop opening, and the date range was also 1 week and always the last date shown.
EU pre-orders ship from various warehouses, mine, e.g., always from Prague. 99% of all my pre-orders arrive on launch day, and are shipped 1-2 days ahead of it.
US receives them mostly directly from China, that's when the bulk shipment to EU also happens, but the individual shipments in Europe are then distributed in one of the EU warehouses.
So I guess it's the same with the iPad Pro - we'll see movement around Wednesday.
