They wouldnt have mayor impact if they were on Switch either.
Okay maybe KH would be bigger if it was on Switch and PS4....but its clear that SE isnt going to leave that PS4 exclusivity train anytime soon.
The Switch release will def. help Fortnite in Japan...just like the console releases of Minecraft helped the IP here.You mentioning fortnite made me curious, how popular is it in Japan? Is it also on ios in Japan?
If the Switch version has the the exclusive local coop mode even better.
