Call your local GameStop, Walmart and Best Buy. Ask them how many NES Classics they've received since launch.
IIRC, the NES Classic launch distribution was indeed in favor of Japan moreso than other parts of the world. But wasn't that Nintendo believing that the product appealed more to Japanese market?
Call it a misguided projection, but I really don't see what Nintendo has to gain by intentionally making something unavailable. It's in their best interest to make products readily available without flooding store shelves with stock.
