Nintendo should handle Switch like they handled the Game Boy. Give it a long life as it's the only viable hybrid console for the foreseeable future, so competition isn't a worry.
More sequels, new games and even create new games for some dormant IPs.
Mario Odyssey 2
Splatoon 3
Mario Kart 9
Pokemon (D/P remakes, Gen 9)
2D Mario
2D Zelda
2D Metroid
Tomodachi Life
Pikmin 4
Animal Crossing spin-off
Splatoon spin-off
I could go on.
