Each of these more or less looks the same as the first one. N64 was a big exception because they did two leap forwards in a row with that and GameCube. Switch graphics are really no different than Wii U so I suspect Switch 2 will catch up to PS4, which again looks no different than Ps5 graphics to me. Finally Nintendo will catch up to the other two in noticable graphics to the majority of consumers (not fps/resolution/HDR fanboys that make up the vocal minority), but really I'm excited about loading times for them. Astral Chains and Xenoblade X had TERRIBLE loading times and I'd like to see those days gone!
I hate to be that person by Nintendo will be nowhere near to catch Sony/MS unless they drastically change direction of how their consoles are designed. Switch is a bit better than PS3 that's fine but PS3 is a 2006 console. I'm not even sure next Nintendo console will catch up current PS4 Pro, let alone PS5
