Square-Enix explains why the Secret of Mana remake isn't coming to Switch

Coming from a RedBull interview with producer Masaru Oyamada...

"Development for the title began before the Switch was announced, so it was definitely beyond our expectations to see the level of anticipation for the release on the platform grow this much. In terms of our current circumstance, we are unable to immediately state that this will become available on the Switch, but we hope to continue listening to the various requests from our fans."

Sounds like there might be some hope for the title in the future, but right now, there's nothing in the works. Again, if we make enough noise, that could change.
