Splatoon 2 is above Dragon Quest XI for PS4 on COMG's pre-order charts already and is even starting to close on the 3DS version of DQXI.
It's coming for you Japan. Hold onto your butts.
Also: I think S-E is making a big mistake not having DQXI for Switch with the other versions. They could have cashed in on that Splatoon 2 craze.
