It's great that Nintendo is going to continue supporting the 3DS

[A Black Falcon]

While it would be kind of nice to have one system that plays all the games, I don't think that I have ever been a single-system-future for several reasons, not least because each platform is different and serves a different purpose. The Switch isn't as portable, has capacitive touch (which is what all phones use and most people prefer, but I would argue is worse for a gaming device because it's so much less precise!), has a screen that must be easier to scratch because it doesn't fold closed, etc. Yeah, it's a portable system for sure, so having a portable and a portable is a little odd, but each one has a different niche.

So yeah, for the future I'm not sure if I'd rather see Nintendo release another handheld, or go Switch-only. I really, really like the DS line of systems, so it would be a shame to end it and replace them with something less portable, and full of games that are often not as designed for short-time portable play. But if they release multiple Switch models or something they could fix many of those issues, and that could well happen, though again Labo makes that difficult.

Yes, I would guess that the most likely thing is that eventually, sometime in a year or so, Nintendo goes Switch-only... but if they don't and released another dedicated handheld I, at least, would be totally fine with that, particularly if it had all those things I love about the DS and 3DS that you can't get elsewhere -- the dual screens, the precise touchscreen, the combination of buttons and stylus, the stereoscopic 3D graphics of the 3DS (seriously, more things should have this!), the folding design which protects the screen(s), etc. I know that between smartphones and the Switch the space for a dedicated handheld is narrow, but despite that for now the 3DS is still selling well, so there's clearly still a place for it...
