FedEx used to be reasonably close on ETA for shipments, but while UPS and USPS has gotten better, FedEx has gotten worse, and it seems like they've just given up completely now.
I ordered something the other day, and the day that the vendor created label for shipping FedEx sent me an email that said "arriving tomorrow". I was shocked.
But that was yesterday and nothing arrived. And this is what FedEx is showing now.

So they're going to provide a date as long as it starts moving.
Based on the screenshot below, it looks like it's moving.
