Super Nintendo Switch (The true superior move to hardcore gamers)

I know it sounds more plausible for it to have to the foretold 2 instead but I'd honestly just'd call it Super Switch instead. Numbering systems is insanely boring and quite un-Nintendo like up to this point.

Switch 2. That's the easiest thing and makes marketing very clear: this is the direct sequel to the Switch.

I think they'll call it Nintendo Switch - Second Generation Model, or something to that effect. Obviously makes it clear that it's a Switch 2 and alludes to that kind of naming scheme. Also based on the OLED Model naming scheme. Really easy to understand and kind of adds its own flare than just slapping a 2 at the end.
