Square Enix is present at the Switch launch with I Am Setsuna but they have much more planed for Nintendo’s latest platform. With Dragon Quest titles confirmed for Japan release, many are wondering about Final Fantasy’s future on Switch. FFXIV is being considered for the Switch and Xbox One according to an official Square Enix twitter post.
Switch support is under "consideration" for #FFXIV just as XBO

This is interesting, as it would be a massive undertaking making a portable MMO JRPG. Granted it has happened before through Phantasy Star Online 2 for the PlayStation Vita and a Monster Hunter MMO on the same platform. Seeing a version of FFXIV on Switch would be quite interesting, so hopefully we hear more about this consideration in the future.
