Fitness Boxing feat Hatsune Miku for the Nintendo Switch be released in an English version?
while there is no official conformation, I predict yes.
the game fist of the NorthStar, which is basically the same game had the English ver released less than 3 months after the Japanese version.
this makes sense because it inflates the profits.
on the other hand if you have a good grasp on the Japanese language it's not much of an issue,
and if you wait you lose on several months of losing weight and getting fit.
