Nintendo games rarely (as in, barely ever) get discounted, especially first party games. Remember how they offered a certain game (I think it might have been 3D All-Stars?) for a limited time only? Nintendo is rather anti-consumer in the long run.
So if you keep waiting for a price drop, it’s gonna be a while. Maybe you get lucky and some third party shop sells it for 40$. Don’t expect it to go under that for a long time, it’s a Zelda game. The ones who really want it will buy it regardless of the price, and Nintendo or the other shops don’t really care about the rest.
I have a what I assume to be about 1500€ to 2000€ machine (I don’t know the exact value as I inherited it from my cousin who passed away in January) and I can play BotW on yuzu just fine. I assume that even a thousand euro machine would be able to handle switch emulation fine, at least if you don’t go doing any enhancements like unlocking the framerate or running shaders…
