The most interesting there is probably Persona 5/Persona 5 Royal.

Jason Schreier weighed in with a comment saying this doesn't mean they're considering it or that it's even possible.

But I still think it's interesting news. If it's not impossible and there's no exclusivity deal that we don't know about, then I'd be very curious to know why Atlus didn't already do this. It seems like one of the most obvious ports to make.

It's not like they don't know...

No clue how Persona Q and Etrian would work on the switch. Both screens are pretty important and a stylus is a very much must have.

Well Sega/Atlus are disgusted with the recent sales.

SMT IV, please. I'm not going to beg for Persona 5 since I have it on PS4 and if I'm not going to get Royal I would not get a Switch port. Persona 4 Golden would be nice but they have not even put that on PS4. I think a Persona HD collection of 1-4 on PS4/Switch would be great.

The map-drawing is more of a gimmick and in newer Etrian games you could turn on a lot of automap features. And other similar games with maps worked on Switch already, like Labyrinth of Refrain.

I'd consider buying Persona 5 Royal, Persona 4 Golden and Catherine: Full Body should they be ported to Switch.

Of that list, Odin Sphere Leifthrasir rings me as a game I'd absolutely love to play on the go with a Switch.
My real most-wanted Atlus game would be Ogre Battle 64 tho, but they are not considering it.

NOT Shin Megami Tensei 4; I just bought it full price on the 3DS and it required me to delete EVERYTHING to fit it. I'd be pissed if it got ported.

I do love it so far though.

If I had to choose it would be the Etrian Odyssey series. Just never got around them.
