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.
I and many people with a Cool PS2 can attest that AMD hardware has no problems running Switch games.
Never heard of that, I assume it’s an emulator. Emulation is different from running a game natively. Yeah, Nintendo probably could get AMD hardware to work as a replacement for Nvidia hardware, but I would guess either compatibility would be imperfect, there would be a performance hit, or both.
Switch 2 emulates Switch 1 games, so being Nvidia or AMD doesn’t really matter there
