Because the switch 1 felt like Nintendo coming back into their own and firing on all cylinders. So many people that Nintendo had lost over the years came back when switch came out with BotW and Odyssey slated for later that year. In contrast, the Switch 2 doesn't have a big defining game yet. Bananza is phenomenal and there could be an argument for it, but it isn't the system seller that I think they hoped it would be. Mario Kart World is just another Mario Kart, and has less content than 8D.
I think there are a lot of people still on the fence. Waiting for something to truly make them want to spend the $500.
