Atlus seems used to release games later on in a console's lifecycle. We have Persona 4 as a big example, but on a smaller scale Devil Survivor 2 was released in Japan on July 21st, 2011, well before the port of the first one on 3DS (September 1st, 2011).
For 3DS, we know for sure about Radiant Historia and SMT. I doubt a classic Etrian Odyssey will be among them: IIRC, the producers said V would've been the last EO on 3DS.
It should be time for 13 Sentinels to show up again too (I'd love for a Switch version to happen, but I suppose the chances are slim due to possible development slowness of any kind).
Anyone with an idea of what could be possibly announced for PS platforms, aside from 13 Sentinels? Project Re Fantasy (platforms unknown) is extremely early (aren't they still recruiting stuff?) and certainly not 2017. The same for SMT Switch (which could be multiplatform, given the HD moniker on the website).
