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.
Backwards compatibility means they might not be able to talk to AMD unfortunately, depending on how the software is set up I’d assume.
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
