Your Switch 1 controllers will work on Switch 2, including on Switch 2 exclusive games

I really didn't expect this to be frank, I thought we'd be forced to buy the new one just to get an extra $114 (AUD, dunno what it costs elsewhere) out of us, would've been an easy way for Nintendo to increase their profit margin.

It's not exactly standard; I think you can use Xbox One controllers on Xbox Series, but I don't think you can play PS5 games with a dualshock 4 for instance.

Correct. Some other examples in history

-DualShock and DualShock 2 are compatible with each other's consoles. One of the few issues is selected games on PS2 that require the rarely used pressure sensitive buttons.

-Atari 2600 and 7800 are compatible with each other's controllers.

I got an Xbox One X in 2024 and it's nice that I can use a Series controller. The used console I got even came with a Series controller instead of an Xbox One controller. 

As I've said, the Switch 2 Pro Controller is still a want for me, but not as required to play games since my Pro Controller is still in good shape.
