Alright, I just received some good news. I ordered an 8GB N4 with bumper case @ 11:52 EST on the 13th and have still not received any tracking info. However, on the 14th I purchased a 16GB N10 which has shipped. So, I was getting worried until I checked out the status of my N10 at UPS and saw something wonderful:

Notice that it states that there are multiple packages. I only have two open orders with them, so I can assume what number 2 is. After signing up for UPS My Choice (Free) the estimated deliver date (Monday the 19th) appears for each Tracking Number.
Now, for the really good news for most of you. My google play store orders page for all 3 items still only show shipping estimates, the receipt for the phone and case still has not updated from the original "order received" status, and neither orders has been officially charged on my card.
Had I not ordered the N10, I would still not have any information about the N4. So, be hopeful as long as you haven't received the back order email!!
