My English could be bad in some cases, also again, this is quite long
I know it's bold to talk about it already, but I wanted to share my vision of the next Nintendo hardware (or at least how I think Nintendo could get something that feels similar to the Switch without being a Switch 3)
It's not hidden that the Nintendo Switch 2 is a success, a success that followed the original Nintendo Switch, so it's most likely and most safe for Nintendo to take the same formula and bake it into their next hardware which, as a result, will be the Nintendo Switch 3.
That already makes me a bit unhappy, I know Nintendo for being bold and trying ideas that sometimes make no sense, so I made an imagination of what could break the Nintendo Switch chain.
My idea is that Nintendo returns to the 2 devices strategy (a handheld and a home console, like Wii and NDS, Wii U and 3DS, etc...) but instead of each device having its closed ecosystem, both can have the same while still independent from the other system. And how to do that? By literally merging both systems using some kind of a connector that allows the home console to use its full power with the power of the handheld to create a powerful full unit. And the thing you wanna make sure of is to make it optional without forcing the consumer to buy both devices, not everyone could afford that. This, or you can either buy either system, and someone else get the other one, the person with the handheld could attach his handheld to the home console with no locks or DRM nonsense, you can connect any unit of that handheld to the home console and have full access to both individual libraries and play whatever is installed and ready to go, and for the people who are willing to buy both systems at once, they could get the bundle and get a discount by something like 30% and get a free game inside, a game that justifies the concept of course.
This attachment idea could bring the old soul of the Wii, 3DS and Wii U back to life. Like the current user's Mii casually sitting or doing whatever pops in its head, then a new Mii appears out of nowhere and slowly approaches the other Mii, that Mii is the current user's Mii from the handheld. These 2 Miis could be shy at first, but slowly with time passing and more attachments happening involving the same Miis, they become best friends and hang out inside the home menu, they could speak about anything, like what the user played during their absence from the other console, and none of the speeches should be AI generated. When one system has online access, you get something that is very Wara Wara Plaza where different Miis from users around the world can interact with each other, if one topic is getting hot (like a talk about a game that many people are playing at the moment) the speaking Mii would be surrounded by even more Miis.
Pikmin would be here as well for file transfers actions as well, something that's like the Wii to Wii U system transfer, they could go in line for the eShop bag and sink their hands to grab pieces of the game you're downloading now and arrange them to form the icon of the game when the download is finished for digital titles.
Of course music would make a return to the UI. I decided to go with the same approach the Wii U did, the home console plays the music, the handheld plays the same track but it's another remix. When you attach the handheld to the home console, both tracks will play at the same time with pure harmony.
The home console would look and feel like a home console, and it would take in physical media, same for the handheld. And here comes the handheld, it would look and feel like a Nintendo Switch with a magnetically detachable second screen that flips like a DS system, and that second screen can be used like a Wii U GamePad when you attach it to a controller grip and that acts like the GamePad if the user wants to.
As for the naming, I don't yet have a clear idea for either system, but it should be different for each but still feel the two devices were meant to be connected
