I am not going to lie. I was not expecting this to happen for a year or two. What surprises me even more are the legs of the game.It sold much less on launch week but it just kept selling on the power of legs. Keep in mind that the Switch has a lower userbase than the PS4 right now. The results are only going to get more skewed towards Switch more and more.
If this can happen with Fifa then one must wonder what other titles can this happen to. I don't think people realize just how much the Japanese market is going to change due to the Switch. It might feel unrecognizable in 2020.
