Nintendo has over 11 billion dollars in the bank and no debts that need to be paid off. They could fuck up so badly they're losing half a billion dollars a year and it would still take 20 years for them to be even close to going bankrupt.
That means the stock would go to shit, but that is a whole another topic about what that would mean for Nintendo, but it wouldn't be good unless they could turn it around like they did like they did with wii u to switch.
But on the topic of console sales, Switch 2 is not going to outsell the Switch 1 unless another covid like event happens, and they have a game like Animal Crossing out right around then. PS2 sales were so hard to beat, because it was the go-to DVD player for a long time, and no physical media format has ever caught on like that since.
Switch 2 is going to clear 100 million units and on every unit they will make a profit on hardware alone. My guess will start off out pacing the Switch 1 sales, then slowly fall behind. PS5 as of late 2024 was at 75million sales, started off outpacing PS4 to slowly fall behind, expect the same here with Nintendo. Worse case right now, if people do say no to buying games at the price Nintendo has set, and in that case, all Nintendo will do is lower the price, much like they did with the 3DS console once it flopped.
As for the console price, Nintendo has no reason to drop it right now; preorders are doing well. What I expect is Christmas 2027 for them to put out a cheaper Switch 2 lite, which is handheld only and will cost around $300, or a home console-only Switch 2 which also costs that if they aren't able to make a Switch 2 lite happen. They will make a worse product cutting features for those that want a Switch 2 cheaper, rather than cut the base model's price.
