According to the rumors there will be more than one Switch 2, they will differ at least storage wise which will be up to 512GB, therefore multiple prices.
If that ends up being the case then it'd probably be 128gb version at $350 and 512gb version at $400.
Actually it would be interesting if they did a real basic model and a premium model right out of the gate (not just storage size difference). Like an LCD and 64gb version for a decent price like $320, and then a premium version with OLED and 512gb which they could then be fine pricing right at $400 since it would be advertised as the premium model so it's alright if it is above consumer-friendly/expected-Nintendo prices. That way cost-conscience people wouldn't have to be paying $350 or more just to get the system and therefore would be more likely to buy the system, but you'd still have plenty of people paying more and giving Nintendo extra revenue by going for the expensive premium model.
This would probably be a much better play by Nintendo than just releasing a single model somewhere between $350-$400. And just make better battery versions of the same models later on like Nintendo did with the original Switch model.
They could later on then still do a Lite at <$250 like $230 or something. And instead of doing the OLED later on, since the OLED would have come out at launch, they could do a Switch Home 4k model later on for same price as the non-premium hybrid model, considering it'd be a little more powerful for 4k and premium performance but wouldn't need stuff like a screen and battery.
Then the whole Switch2 family eventually would be Lite, Hybrid, 4k-Home, and OLED Hybrid for say like $250/$320/$320?/$400.
450 with an LCD screen and 64gb storage
500 for the premium: oled screen 128+ GB memory and better battery
lol 0% chance, but I assume you're joking. This would be a perfect way for them to guarantee a bad generation for Nintendo haha
