There's plenty of stock in smaller countries. I live in New Zealand and if I walk into any electronics retailer, I'm guaranteed to see a bunch of these in the gaming section. I've heard similar stories from people that live outside of the US.
But it kinda does justify the view that they are bungling this release if they have stock left on shelves in those countries while those in US / Japan (where I am) can only resort to buying in secondary markets.
Even phyisical copies of Zelda are very hard to find, and with Nintendo's crazy download pricing - I wanted a physical copy (70 eur for the downloadable version of the game vs 60 for the physical - really?).
