Fallout 4 would be nice. Not sure if it classes as AAA but would also like to see Sonic Racing Transformed ported over. A nice racing game that would suit Switch and be perfect at 60 fps docked, current home console versions are 30fps and it always felt like a game that would benefit from 60 fps. I'd be quite happy with a 540p 60fps version in portable mode.

Fallout 3 and/or New Vegas Remaster.
The Evil Within 1+2.
Crash bandicoot Collection.
A Monster Hunter game (I have a theory. After MH World underperforms, Capcom will try to bring XX to the West, only to uderperform as well because nobody cares anymore about that particular title).
Plants VS Zombies. Garden Warfare.
Another Darksiders port.
Bioshock Collection.
A Far Cry game (either one is fine).
A Digimon game.
Batman Arkham Collection (Asylum and City, not Knight or Origins).
A Final Fantasy Tactics Remake.
A Final Fantasy HD Remaster (between IX and XIII)
The Sims 4. Switch Version.

I think GTA5 is probably in the pipeline. That games is some $$$ for Rockstar and its pretty much been ported to every system outside of portable/mobile. Some Nintendo-only gamers probably are hungry for some GTA again.

Outside of that I don't believe Bethesda would do something too soon and probably are waiting to see how other games of theirs perform once released (Doom and W2). I have a feeling though we may see some sort of FF game announcement (like maybe FFXIV) in a short time.

Hoping Overwatch is a possibility.

Overwatch
Next year's Call of Duty
Grand Theft Auto V

Persona 5 Crimson. Pls?

Overwatch.

Not next, but I'm willing to bet CoD2018 will be coming to the Switch.

I think FFVII Remake will be coming. That Cloud in FF was just too odd and out of the blue for nothing to come of it.

Glad im not the only one! Its already coming to PS4 and XB1. And plus the touch screen will make designing your sim and your house much easier! If they implement the touch screen feature though.
