Exactly.
It seems that each country was allocated a certain number of models, which would make sense due to differences in import policy and the likelihood for different geos to have different preferences. It certainly should not be shocking as when (for example) a new console launches, not every Target will get the same quantity of each configuration. Nor will the supply and demand for each model be equal at each store.
It seems like the queues go by...
1) Geo (US, UK, China, etc)
2) Model (SS w/ Black band, SS w/ link, etc)
3) Time (Order time at 12:01, 12:02, etc)
Agreed. Unfortunately, it looks like they definitely allocated certain models to certain countries in anticipation of "taste" (who knows how they did this, market research?), but they did this poorly. I would've expected the black sport band variants to be heavily supplied to the USA, which is the opposite of what was done.
