I'll probably keep my Switch OLED at least for a while and for some comparisons... maybe even until a Switch 2 OLED arrives in a few years.
I don't want to clutter the new handheld instantly with my digital Switch library, so I'm planning to only install Switch 1 games on the Switch 2 with enhancements... especially as long as the microSD Express cards are that expensive.
But keeping two Switches active creates a new problem... which of them will be set as the primary console and which has to be the secondary console?
One of them will get problems to access my digital library when I'm not at home. So I probably keep my Switch OLED at first as primary, because I have soooo many eShop SW1 games on them which won't get Switch2 enhancements. On the other side, all of my SW1 games, where enhancements are announced, are physical cartridges.
But it's only a matter of time when I get some digital SW2 games or some of my digital SW1 games get enhancements. The bundled Mario Kart World will already be my first digital SW2 game... and if I'm honest I'll probably ignore my unenhanced SW1 library as soon as I play the new and enhanced games... so better set the Switch 2 as primary console?
Or is the best solution to create a new Nintendo account for the Switch 2? Then I could set the primary console for my new account to the Switch 2 and leave the primary console of my current account on my Switch OLED. Then add my old account as secondary on the Switch 2 and add my new account as secondary on my Switch OLED. Any downsides for that solution?
