I doubt the number of people importing from other regions is high enough to significantly skew the proportions.
We can`t be sure. On the Japan thread we had PS5 basically selling 1M units but 500k SW, one of the big suspicions is that most of those purchases are for exports. But again the main point on my end is that with supply constrains we can`t really infer anything, Xbox Series X is sold out in basically every market so we don`t know if the supply was enough would the percentage increase for USA or would decrease.

Mr Puggsly: "Hehe, I said good profit. You said big profit. Frankly, not losing money is what I meant by good. Don't get hung up on semantics"
Azzanation: "PS5 wouldn't sold out at launch without scalpers."
