I managed to get an order in for Ni No Kuni Wizard edition yesterday over the phone and mine has shipped out today.
Anyways I will try to see if I can help those that received a shipped email but no tracking number.
Go to the UPS website linked
here. Click on the "Track by Reference" drop down menu. In the "Shipment Reference" box put in your Namco order #. For "Shipment date Range" put in dates ranging from this Sunday to today. "Destination Country" as United States, and your own Zip Code. Hit the "Track" button and UPS should give you a tracking number for your package. Hope this helps some of you guys out.
^The above method probably will work for those who did not get a shipping confirmation depending on if Digital River made a shipping label or not.
