For myself I would absolutely LOVE:

1. F-Zero
2. Metroid
3. Donkey Kong Country or 3D Donkey Kong
4. Pokemon (Open World like Breath of the Wild, highly unlikely)
5. Proper StarFox

1. Metroid (Prime 4)
2. Diddy Kong Racing 2
3. Pikmin 4
4. Star Wars: Rogue Squadron (remake or 4)
5. Super Mario Sunshine HD
6. F-Zero
7. Luigi's Mansion 3

They really need to bring Super Mario Maker over. Really, given the nature of a game a port with a few additional items is all that's required.

I imagine they're waiting till they get their online services up and running fully though.

1- Advance Wars
2- Metroid
3- FFVI Remake
4- Contra 5
5- Double Dragon Reboot

Call of Duty Switch

Pikmin 4
Smash Switch (plz have more characters and a story mode)
Pokemon openworld
3D kirby game
ace attorney game

Kirby Air Ride 2

Baten Kaitos

Mischief Makers

Kid Icarus

Tales of

Atelier

I'll be happy with at least 2 in this generation

Monster Hunter V (New MH game exclusively developed for the system)
Pokemon MMO
Metroid Prime 4
Fire Emblem X SMT 2

Oh Contra 5! That's a good call. Would love to get in some local co-op run 'n gun action on Switch.

I wonder what WayForward is up to.

Open world pokemon rpg (or any main series pokemon game for that matter)

A follow up game to Zelda Breath of the Wild (open world termina perhaps?)

An animal crossing that greatly expands on New Leaf's core mechanics ( a greater scale too)

Also these two games aren't unannounced, but:

Farcry 3/4 and Assassins creed IV (ubisoft, I and many other people will take these games over Just Dance and Steep)

Gta 5 (again, Rockstar, LA Noire instead of this!?!?!Are you kidding me!?!?!)
