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.
Japan is one country though, globally is a different story. And wouldn't MS just be shipping more to the US and less to other places if they could sell more that way?
Bet with Liquidlaser: I say PS5 and Xbox Series will sell more than 56 million combined by the end of 2023.
