Done what on one device? Nintendo has been explicit, going back to the Wii, that power conversation of their TV consoles is a priority.
Communicate what? What are they trying to communicate? This is marketing 101, what is the message?
Ya'll are acting like I'm trying to advocate for or against a name. I'm not. I could not give a rat's fart what Nintendo calls the next machine that lets me play Zelda, because "can play the next Zelda" is the only piece of information that they need to communicate to me in order to get a sale.
Nintendo puts in every damn corporate message that their whole philosophy is integrated software and hardware, yet everyone seems to think that the only thing Nintendo needs to say with the name is about the hardware.
And that the only message about that hardware that needs to be communicated is "it's a more powerful version of what you already own".
And that Nintendo, a company whose entire 21st Century mission has been defined by the failure of the GameCube, a console whose sole pitch was "a more powerful version of what you already own", is totally cool with trying it again.
I have argued that I think Switch 2 could be a good name, because it could also be used to describe sets of software features that I think are natural extensions of what Switch does, not just because of how it describes the hardware. That doesn't mean I think it's the only good name, or that it will be the name.
I just get frustrated by people who think Switch 2 is a good name because they can't engage with the idea that Nintendo would ever deliver anything but a 4k60 Breath of the Wild machine, and that Nintendo might want to communicate a more complex idea.
Yes, it is very clear, which happens to be useful, because that's exactly what Sony made. If, however, Nintendo had called the Wii "GameCube 2" I doubt it would have been a useful designation. Nor do I think "DualBoy" would have been a better name for the DS. Or that "DS2" would have been a clearer description of the 3DS.
Nintendo has had unified naming conventions for families of systems before - the non-TV consoles were "boys" - the GameBoy the VirtualBoy, the Game Boy Advance. Until the DualScreens - DS/DSi/3DS/New 3DS. The Nintendo, The Super Nintendo, the Nintendo 64. And yes, the Wii/WiiU
75 million people bought a 3DS, and understand Nintendo's history with naming. And some subset of those people like Nintendo because they do things differently, whereas I cannot imagine a single person who would be put off of a new Nintendo device because it had a silly name.
