i'm hoping for an actual loving friend system
The Japanese have a different culture around multiplayer; to them, it's about playing with (and only with) people you know personally, hence the idea of friend codes which you can distribute to your real-life friends and play with them when you're at home. Our culture is more open to the idea of playing with people you've never met before.
This is why the Friend Code system sucked for us, but I doubt it'll change much as Nintendo is very strong-willed about their Japanese culture and history.
is it only botw or are other games 60 fps
Only BotW. From what I've heard, Mario Kart 8 will run at 60FPS (except in splitscreen), and Splatoon 2 & 1-2-Switch were observably running at 60FPS during their demos.
