I ordered my 32 GB Nexus 5X on 10.29 (Black). I have not received a shipping confirmation from Google yet, but I just searched by Reference number on the FedEx web site using the last part of the order number (following the period) and along with my Zip code found that the label has been created with an anticipated ship date of today (10.19) and a delivery date tomorrow (10.20).
I selected the overnight shipping option, my last name begins with "P" and I am in the US. The phone appears to be shipping from Carol Stream, IL.
YAY...I can't wait!!!
