It sure will. It will sell 195k and hell will break loose ;)
I would think this port is made for non japanese market in mind. YoKai Watch has seen decent success in Europe on 3DS so it makes sense for it to be on two popular platforms in Europe (Switch/PS4).
If that port is truly made for the west in mind, then it's even worse.
L5 western releases are a bit of joke when there's no publisher backing them (Nintendo, Bamco). Yo-kai Watch without Nintendo's backing is pretty much a disaster waiting to happen.
Fantasy Life 2 is the only L5 game that could sell 1 million copies worldwide
I would love a FL2, but nah, no way in hell it would ever sell that much.
