To some extent I can understand since they're expecting a certain ROI on the console which would include American sales, and therefore if American sales drop because of tariffs they need another way to make up that lost revenue.
That being said I feel like it would be a mistake to make that up by increasing the price of the console for other markets too. In my opinion if American sales drop then they should pivot their focus to other markets until American leadership stabilizes, i.e. stops being an active detriment to the American economy and all the international companies involved in it. Which likely won't happen until trump/his administration is out of office.
