The answer to this question is relatively simple: Nintendo is home to some of the most successful franchises in video game history, including Pokémon, Super Mario Bros., and The Legend of Zelda. Because these IPs are owned by Nintendo, their exclusivity on Nintendo devices means that there is barely any competition in the market. If you want to play the newest Pokémon or The Legend of Zelda games, your only legal option is to buy a Switch, because those games will not be available on other platforms. Because of these factors, Nintendo tends to keep their exclusive titles at the original MSRP for long periods of time.
