Nintendo

Xenoblade Chronicles & X

Super Mario Maker

The Wonderful 101

Kid Icarus: Uprising (would be nice to play this game with controls that doesn't murder you)

Super Smash Bros. 4

Squeenix

Final Fantasy XII

Terranigma

Chrono Cross

Valkyrie Profile 1 & 2

SEGA

Valkyria Chronicles 1-3

Vanquish

Namco

Xenosaga 1-3

Switch should be able to handle any 7th gen game... so I'd like if all publishers port and enhance all their best and popular non-exclusive 7th gen titles to the Switch.

"Red Dead Redemption 1: Definitive Edition" would be nice. Launched together with RDR2 for PS4/XBO (they could combine the marketing of both products).

The last time I tried to play my PS4 in the bathroom it didn't go so well. 

As for the main post final fantasy 4-10, 12 and 14

The entire mgs series specifically 3

Monster hunter

Red dead redemption

Okami 

Xcom 1&2

Problem is that the touch screen can't be used if docked

Add Mortal Kombat 9 while  you're at it so Switch users would have the whole reboot story (and not just the latest entry like Mass effect 3 on Wii U)

Throw in both Injustice titles (first one was on Wii U as well, so porting that one shouldn't be a problem at all), SF IV + V while you're at it.

Oh, and both South Park games, should run perfectly on Switch.

Fallout 4
Grand Theft Auto V
Resident Evil 7
Dragonball FighterZ
Monster Hunter World

RR5,6 and 7. Burnout paradise/takedown and the other 1. The name escapes me.

Mario maker. Bitches!!!

Some games that I always think about when people talk about Switch ports:

Okami HD - Already mentioned on OP, but it was on Wii, and the sequel was on DS, so I mean yea.
Disney Afternoon Collection - Apparently, putting a compilation of NES games on everything except a Nintendo platform makes 100% sense for Capcom.
Dragon Ball FighterZ - The hot new fighter on the scene, I doubt the Switch couldn't handle this.
Kingdom Hearts 1.5 and 2.5 - Nintendo handhelds got a lot of spinoffs, give a Nintendo platform a taste of the main series already.
Overwatch - This was a game I was fairly confident would get a port when the Switch came out. As time goes on though, I feel like mainstream appeal for this game isn't as big as it was, so I am starting to think it wouldn't be worth Blizzard's time at this point
Persona 5- I JUST WANT THIS OK?

The world ends with you is coming to switch...
so ports of some other great DS games would be great. I am thinking Hotel Dusk: Room 215 and Last Window: Secret of Cape West
also GTA: Chinatown Wars, just so that switch would have at least one GTA :D

The increasing closeness between Nintendo and Bandai Namco makes me hopeful fro a Xenosaga trilogy remaster, which is probably the port I would want the most. Also Xenoblade Chronicles X would be nice, other games I'd like to see as well:
Final Fantasy Type-0 HD
Final Fantasy XIV
Final Fantasy XV
Final Fantasy XII
The Last Story remastered
Skyward Sword
Windwaker
Super Mario 3d World
Super Smash Bros 4

Other than FF it's mostly just Wii U titles now that I reflect on it, which makes sense considering it's the only Nintendo console I never owned. A lot of what I wanted in terms of ports have already been announced/released such as Mario Kart, Splatoon, and Hyrule Warriors.
