Update: Microsoft has also revealed that these games (with the exception of Crystal Chronicles) are coming to Xbox One, as well. The time frames will be similar to the Switch.

The original story is as follows:
During today’s Nintendo Direct, Nintendo announced that multiple Final Fantasy games in both the mainline series and spinoffs are coming. Final Fantasy VII, IX, X, X-2, Final Fantasy XII, Chocobo’s Mysterious Dungeon, and World of Final Fantasy (titled Maxima) are coming to Switch, in addition to the previously announced Final Fantasy: Crystal Chronicles and Final Fantasy XV: Pocket Edition.
This is the first time the PlayStation Final Fantasy games have ever been ported to another console, long-assumed to be locked to Sony hardware due to an early-2000s investment Sony made in Squaresoft. Sony sold off their stake in Square recently, perhaps paving the way for the Japanese RPG giant to release the well-loved Final Fantasy games elsewhere.
World of Final Fantasy Maxima releases November 6, Final Fantasy XV: Pocket Edition releases today, Chocobo’s Mysterious Dungeon is this winter, while everything else is 2019.
