Generally speaking, I doubt Square Enix can make any really good games moving forward. They seem to have completely lost it, with some few exceptions aside. At any rate, given that this is coming out on Vita, there is absolutely no reason it is not coming out for the Switch as well. Square Enix have been making some terribly odd business decisions, and I won't be surprised if we see them struggling to survive down the road.
That said, the original Secret of Mana was a masterpiece. Wonder how long more Square Enix can rely on either ports and remakes, or really drab and uninspired sequels. Something has to be done, or they will perish in the dustbins of gaming history.
