I have to imagine the Steam Deck playing in the same price bracket (the refurb base model was going for $320), Nintendo _may_ feel the pressure to support backwards compatibility. Why buy a new device and Breath of the Wild over again when you could just get a Deck and play a large % of ever PC game to have ever existed?
Nintendo is also in a different position this time around, as the WiiU, DS, 3DS, etc had such different hardware that remaking a game for the Switch was essentially a necessity, whereas I expect the Switch 2 to be a Switch with faster hardware.
