I've already played it, but The Talos Principle would be great on the Switch. Since it already has a version for the Nvidia Shield it should be super easy to port over anyways.

When Square Enix turns Kingdom Hearts III into a mobile game somehow I'm sure we'll get it.

I just beat Tales of Berseria. That game could run on Switch with ease.

'Tales of' is a series that I personally would really want on the Switch and was especially happy when Bamco counted it as one of their franchises that will make an appearance on the Switch.  The series uses a cel-shaded style so it shouldn't be too demanding on a hardware level and the main audience for it is Japanese, the market that the Switch almost caters to, so it should make complete sense for the series to have multiple games on the platform.   To this day, I'm still miffed that we still haven't gotten the complete version of Tales of Vesperia ported to the west and I hope that's one of the first Tales of games that Bamco puts on the Switch since it's considered by many to be one of the best (if not the best game) of the series.  Hell, it was one of the main reasons I even got a xb360 years ago.

There really isn't any excuse not to port GTA 5 other than Rockstar just being dicks. 

I would really love a WWE game that's like the early Smackdown games, I'm not as big a fan of the more simulation-based gameplay.

Overwatch doesn't make sense for the switch. It doesn't even make sense on console, yet alone on a portable device.

Screen is too small and the controls would be too far away from the pc version.

I haven't played too many Tales games yet, but would really like to get more of them so I have the chance to :p

The 3DS got one Tales port, so hopefully the Switch isn't just getting one either, but it's definitely a good start
