Regular: $499
Cartridge version: $599

399 sounds like the inevitable outcome if we want a decent piece of hardware for 6-7 more years. Even so, I don't like how a portable console from Nintendo, which is supposed to be the cheapest way to enjoy a brand new generation of gaming, is reaching prices that reseamble that of some home consoles of the past. Hybrid or not, I don't like it xD

Edit. Double post

I think $400 is the floor now.
Hopefully not more, but it's possible given the price of components today.

400-500

With a lot of luck, $349. More likely, $399.

Of course it will be 20-30 € more expensive in the EU and only God knows how much more for other markets (UK, Australia, Canada, etc.)

$400 for digital-only
$450 for a cartridge slot version and maybe some other improvement.
I'd love for them to start at $350 to have an option half the price of PS5 Pro.

Wii cost 250 USD when the Wii was release in 2006, it will be about 410 in 2025.
Switch cost 300 in 2017, which is about 385 today, it will be about 395 in 2025.
Wii U cost 350 in 2012, which is 480 today, or about 492 in 2025.

Wii U was considered expensive in 2012, while Wii and Switch were considered cheap. But Wii U was largely considered expensive because of its controller. Switch 2 at a higher price would more likely be perceived as priced for higher value - similar to how hybrids can go for more than handhelds because of a perceived higher value.

That said, I think the price will likely be 430 to 470, with a low end of 400 and a high end of 500. The most likely price point being 450.

If you live in Canada (as I currently am), Switch in 2017 launched at 400 CAD, which is 500 CAD today, so expect about 560-600 CAD for the Switch 2. Most likely Canadian price being 580.

$499 at launch. Including a mainline game like Mario and a 'Gimmick' game like Duck Hunt. (referencing NES Launch in my country). So later they can lower the price excluding pack-in games to $399.

Any higher than $399 might pose problems I think
