I've been similarly thinking about this on and off as well IanSane.
I think they have to raise the price on the system as we know it now... but introduce a lower priced SKU with the dock, HDMI cable, and charging grip stripped out. There can still be a "Complete" SKU at some eye-watering higher price, but this "Core SKU" would be able to preserve some lower price as an introduction to the ecosystem. A handheld Switch 2 is still a complete system, and you can always buy a dock separately. Pre-tariff the price of an extra dock was $109.99... so that'll still hurt, but at least you get your foot in the door.
As for the games... honestly I have no answer for that. Physical games will get hit hard if these tariffs stand. And there's no wiggle room as to what goes in the box. So... maybe the solution is to go *SIGH* all digital, which makes me cry as a person who prefers physical copies, but it's the only way I can see to mitigate these painfully high prices.
