I’m replying to both of you at the same time as my response is the same. Nintendo has referred to the Switch as a Family of systems, aka a brand. So maybe instead of thinking of the Switch as an individual system, even a group of systems, it’s really a brand of consoles made by Nintendo. Think similar towards Microsoft with Xbox, or of course Sony with PlayStation. Nintendo might be shifting their focus to make the Switch a brand of consoles that'll span generations rather than only a few short years like they’ve done since the SNES in the console space.
But as Concert mentioned, the Game Boy was really just a brand of handhelds, which over time received improvements, whether aesthetic, comfort, QOL, or even graphical improvements. Ultimately, they were all just a Game Boy. Ask most random folks out there who are not gamers, and they'll know what a Game Boy is, even if they don’t understand the differences between the first one to the last one. Branding can have a massive influence, and we’ve seen this with PlayStation globally, and Xbox primarily in the Western countries.
The Switch to me feels like a restart from Nintendo in terms of branding, and it'll continue for the foreseeable future. Now, how does that pertain towards May 7th? Nintendo could just say they expect “the Switch family of systems to continue growing into this current Fiscal year.“ While I would love for them to tease something, it may not end up occurring.
Switch 1, Switch 2, Switch OLED, etc, etc. None of that truly matters because Switch is successful enough to be a brand within itself of Nintendo. Non-gamers may not understand the difference between a Switch 1, and a Switch 2, but they'll understand what a Nintendo Switch is. Nerds will know the differences between each year of the Ford F150, but the average person will just know it’s an F150, and it'll do truck stuff, and that might be good enough for them.
