Nintendo and Square Enix have announced Final Fantasy VII Switch alongside various other Final Fantasy games, including Final Fantasy FFIX, FFX/X2 and FF V. Final Fantasy XV Pocket Edition HD, Chocobo's Mystery Dungeon, World of Final Fantasy, and Crystal Chronicles will also release on the PS4. This not only includes the legendary Final Fantasy VII but IX, XII and X/X2 HD.
The first game is Chocobo's Mystery Dungeon Every Buddy, and it's a souped-up version of 2007 Wii title Final Fantasy Fables: Chocobo's Dungeon.
2019 will see the arrival of eight - yes EIGHT - Final Fantasy games, which is probably a billion-ty hours of gameplay right there. That has changed, as the recent September 2018 Nintendo Direct revealed that almost all of the PlayStation and PlayStation 2-era Final Fantasy games will soon release for the Nintendo Switch.More news: EU parliament opens punitive action against Hungary for damaging democracy
Aside from Nintendo's notable omission of Final Fantasy VIII from that robust lineup, the reveal pretty much brings Nintendo up to date on all the mainline Final Fantasy games up through Final Fantasy XIII, which released for the PlayStation 3 and Xbox 360 in 2009 and hasn't been ported (so far) to any current-gen console.
Lastly, a new mini-game where you'll get to go fishing with Noctis. It's slated to come to the PlayStation 4 and the Nintendo Switch this winter.
Of course, that's just speculation at this time.
