Thanks for the link. I use my Switch in docked mode 95% of the time, but I do take it to my parents every month or so. The 7" screen would be a boost for my low vision. I have registered my interest. Hopefully Nintendo will have a flag on my account as being a genuine customer as I have ordered from their store before.
Presumably the existing Pro controller will continue to work with it?
What would be the best way to transfer save date between consoles? Does it need the Nintendo online account or is an SD card sufficient? Saved games I need would mainly be Mario Odyssey, 3D All-Stars (Mario Galaxy), Super 3D World + Bowser's Fury, Super Mario Party, Mario Kart, Smash Bros, Zelda Link's Awakening and Sonic Mania Plus. Not essential, but the progress on 51 Worldwide Games would be nice to have saved as well.
Your Pro Controller will work fine, you'll just need to pair it to the new console.
As per the video Raiden posted transfering your account and save data is fairly simple, but the games aren't transferred, you need to re-download these.
My concern is Animal Crossing, there is an island transfer tool but I'm a bit confused, do you transfer your user first and then use the tool or what?
I don't know why there isn't a simple process to clone one Switch to another, but Nintendo have been useless with digital ownership and accounts for years.
