I think the $450 USD was just keeping up with inflation.

$300 in March 2017 when the switch originally launched is equivalent to almost $400 today ($392 and some change). S2 is launching at $450, if they were only expecting 15%-ish tariffs then maybe, but it should then be cheaper outside of the US if tariffs were the only reason. Electronic component prices have gone up beyond inflation growth, I think it would be easier to blame it on that.

$80-90 games before tariffs sucks, but games have been $60 for as long as I can remember, and they’re only getting more expensive to make.
