MobaPad is a Switch controller and game case maker (that I have never heard of), so they should have reliable info. They said that:
- The Switch 2 will have physical cartridges and the slot will also be able to accept Switch 1 games.
- There will be a new button on the back of each Joy-Con, behind the triggers.
- There will be a new button on the right Joy-Con, by the Home button.
The 3DS had backward compatibility with physical DS games. The Wii U had backward compatibility with Wii games (the Wii could also play GameCube games). No surprises here - especially if they are going to call it “Switch 2” I’d have been surprised if it wasn’t compatible.
3DS cartridges had an extra notch on them to stop them being inserted into a DS. Probably we’ll get something similar here or there will be some software mechanism to stop attempts to run the new games on the old system.
You can also do the opposite though. The Switch had 0 backwards compatibility. The GameCube, N64, and SNES had 0 backwards compatibility. Hopefully this article is legit.
True, but the Switch was a big rethink so retaining backwards compatibility would have been tricky.
Switch had the worst kind of “emulation” where nearly all the best games for Wii U were re-released for Switch at a higher price.
