Update: between my comment above and now, Amazon has marked the other two items shipped, and un-slipped the expected delivery date back to the 20th. Interestingly, the "shipped" status is matched to a tracking update that says "package left the shipper facility" with no time or location information. All further updates have a location and a timestamp. (Everything is shipped by Amazon.)
