TL;DR: Nintendo of America president Doug Bowser discussed with Wired the impact of new tariffs on the Nintendo Switch 2, which may increase its price from $449 to $600. The tariffs affect manufacturing in Vietnam, Cambodia, and China. Nintendo is assessing the situation, having already moved some production out of China.
The games don’t drop in price, but the consoles do. There’s even a chance the price could go down for the holiday season, even if it’s something miniscule. This launch price is the early adopter tax.
