I'll just be content with a fix to the drift issue and a bigger handle thing for whatever the new Joy Cons are called so my hands don't feel cramped playing with them. Adults play your consoles too, Nintendo.
I love my Switch Pro controller, more than most other ones, but this really frustrates me. I have to switch to a different one for practically any racing game
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.
Just because the slot can read Switch games, does not mean that the console is 100% backwards compatible. It could be that only select games (those with compatibility patches) will work or maybe the console will be able to validate the cartridgeto allow you to get a discount on buying the remake from the digital store.
These are worst case scenarios, but don't go selling your Switch yet.
