I just hope that Nintendo is caring more about TV mode users in their next gen. Switch Lite and OLED were just an option for handheld users.
Backward compatibility is a must. I'd love to have faster loading times, but I don't know if it's possible to read the gamecards faster.
1080p60 in every game in TV mode would be fantastic. I don't really care about 4K. If it's upscaled I'm fine. Please put an option in the system settings that you want to prefer performance over resolution.
