The 1967 Corvette:
The 1966 Corvette it was directly replacing:
If this new system were identical to the current Switch but added a couple small new features, then yeah, give it the same name and an indication that it's a slight upgrade. Like Nintendo Switch Lite, or Nintendo Switch OLED.
But it's not just the same thing with a little upgrade. It's a new thing. And even if it's considered part of the same product line (which it very well may be and I almost expect) there are still much better, more creative, more interesting names to indicate a new generation in the product line besides "2."
Nintendo has almost never done that. The only time they ever did was on an obscure Super Gameboy upgrade that never made it out of Japan. It is very much unlike Nintendo to go that route, and the only game console manufacturer afaik who ever even
has is Sony.
Granted, I'm not saying it's impossible for Nintendo to do it, just that 1) it'd be way out of character for them and 2) I'd personally hope for a name with a lot more personality. If they had done what Sony did then the Super Nintendo would be Famicom 2, the Nintendo 64 would be Famicom 3, the GameCube would be Famicom 4, like.. how
bleak would that have been?? I just hope for better. I hope for
fun. It's Nintendo fer chrissakes.
