the price of the old nintendos wasn't necessarily dropped... It was unbundled. The original had 2 controllers, and the most popular game as a pack in. The later price dropped versions, had one controller and no games to play at all. If you wanted couch multiplayer, and the game everyone else had, you had to pay for them separately which brought the price right back up (or over) the original price. the 'discounted' switch without the bundle, is already available now. You can save $50 NOW by buying the switch 2 without a game without having to wait for the 'price drop' years after launch.
SNES controllers didn't cost a ton, but the games where 55-70 dollars each. this makes the '$100-$50' price drop more like a ~20 dollor price drop, and it was significantly into the products lifespan.
