I do hope Nintendo use better quality screws on Switch 2, as this is a problem that has likely caused no end of problems for repair technicians. I have repaired a Wii before and its screws were of a far higher quality.
I'd go further and say I'm hoping one of the reasons for the higher Switch 2 prices is better quality components overall. I loved my Switch 1 but good god the build quality was disappointing, in particular for the joycons - had so many problems with those.
One of the reasons I'm holding back on a potential Switch 2 purchase is that I want to see someone do a really good teardown of that console when it's out and see how much they have improved it. If we can go back to the good old times where we joked that their consoles were built out of "Nintendium" I'd say the $450 price tag becomes a lot easier to digest.
