Based upon my order experience, I wouldn't put too much stock in what shows up on Moto's order status screen. Once they show that your device is being built, it's a long time until they actually update that screen.
I ordered my phone within a half-hour of the preorders going live. My device "being built" stayed in that same status for what seemed like forever.
My original shipping date was 9-15-15. However, my phone is currently in Memphis today, and based upon FedEx's Delivery Manager, my phone should arrive on the "shipping date".
If you sign up for FedEx's Delivery Manager, you can access that screen whenever you want. Once a FedEx shipping label is created so that you have a tracking number, THEN you can actually see what is happening with your new phone's delivery status.
Don't put too much stock in Moto's "Order Status" page.
