No way. If Apple wanted them delivered later in the day, they would have used a different shipping rate (overnight standard?). Believe it or not, Apple doesn't have that much clout with FedEx. Once the packages are in FedEx's hands, FedEx controls the delivery protocols, not Apple.
Apparantly they do. Just got this on my priority overnight package that said 10:30am delivery:
"10:17 AM - Delivery exception - Future delivery requested"
