Core Viewpoint - The resale prices of the Nintendo Switch 2 have decreased significantly on the Mercari platform, with most items now priced between 70,000 to 80,000 yen, down from initial prices close to 100,000 yen, indicating a shift in the resale market dynamics [1][2][3]. Group 1: Resale Market Dynamics - Prior to the official release, resale prices for the Nintendo Switch 2 were as high as 100,000 yen (approximately 4,973 yuan), but have since dropped to a range of 70,000 to 80,000 yen on Mercari [1][2]. - The highest confirmed resale price was around 90,000 yen (approximately 4,477 yuan), which is about double the suggested retail price of 49,980 yen (approximately 2,637 yuan) [2]. - The decline in resale prices is attributed to the presence of a large number of listings on Mercari, leading sellers to adjust their prices downward [3]. Group 2: Seller Behavior and Market Regulation - Nintendo implemented strict measures to prevent high-priced reselling, including conditions for lottery sales that require applicants to have over 50 hours of gameplay on existing models [3]. - The emergence of "amateur resellers" is noted, as individuals who are not typically involved in reselling are now participating due to high competition for lottery entries [3]. - Despite the price drop, consumer criticism is directed at Mercari for not effectively regulating resale prices, with concerns about the balance between free trade and necessary regulation [4].
