A lot of them have - there are a few who ordered at the tail end of November (Bitcoin Black Friday was when it went insane, so pretty much from order 600 onwards) whose orders shipped out on December 19th-23rd, and they're still awaiting the arrival of their parcel. Unfortunately once it ships we have no influence over it, and the shipping method the person chose + import customs at their country + a roll of the postal services dice will affect how quickly they receive it.
