Switch 2 will be backwards compatible with Switch

This shouldn't come as a surprise to anyone. Nintendo has had a trend for the past couple decades of releasing "sequel" consoles that are essentially a modernized version of the old one with extra features, compatible with everything that released on the predecessor.

With all three major console manufacturers prioritizing backwards compatibility, and the rise in PC gaming (universally backwards compatible), people are starting to catch on to the fact that old games don't "expire" after 10 years. I wouldn't be surprised if backwards compatibility just becomes the standard for all gaming consoles going forward.

Tangential, but I'm also interested in seeing how games that released on old consoles and are continued to be played, like Fortnite, will support aging hardware. I don't like that Epic can one day announce the game just no longer works on that console, rendering your purchases null and void until you upgrade your hardware, but I can't expect them to update that version of the game forever.

Isnt it pretty much just the Wii and Wii U? I guess you could play GameCube disks on a Wii but calling the Wii a modernized version of the GameCube is a real stretch.

GB/GBc/GBa, DS/3DS (we don't talk about DSi) come to mind if you count them as consoles. You can even play GBa in the original DS, but not in the 3DS as far as I know.

DSi XL (LL) is actually my favorite way to play DS games because the screen is huge (and IPS!) but is in the native DS resolution of 256×192 pixels. DS games on 3DS-derivatives look like blurry garbage because they get scaled up to 320×240px for display on the 3DS's 800×240px (400×240px per eye) panel.
