No I think you will see bigger upgrades than things like 3DS XL and New 3DS and 2DS ... those types of things don't excite consumers. None of the 3DS revisions caused a notable increase in sales for the 3DS, whereas XBox One X has caused a very noticable increase in XBox One sales and PS4 Pro is helping the PS4 with higher than anticipated sales for being in the back half of its hardware cycle, so much so that Sony had to revise sales expectations up.
"Pro" models have been helping Apple and Samsung sell more phones and tablets for years too.
People like the premium model, I'm talking bigger than things like 3DS XL, PS4 Slim, XBox One S, or even New 3DS.
A New 3DS type revision for Switch alone is not really gonna lit many people's world on fire. It's 2019 almost, you gotta bring more to the table than that. "It's slimmer and has a few new features" doesn't cut it, it's not 2004 anymore.
There will be a slimmer/smaller/more power efficient Switch sure, but that won't be the only model Nintendo sells, a Pro model is gonna happen eventually too IMO, one that has a significant upgrade. And Sony and MS will also release new model PS5s and XBox 2s 3-4 years into that cycle. It's simply going to become the new normal and it'll become more like the PC side where generations become basically blurred.
