Osaka potentially having a much higher presence from Nintendo themselves has to factor in, at least a bit. It's not an especially common occurance for that to happen at Epic, so things can skate by a bit more.
I agree with the above point from
@mccgavin though. I think the primary factor is it being in Epic itself. If SNW was added to USF like it was planned to, it might look a little cleaner than it does now. SNW is an already complex land, DKC even moreso, that is now saddled on the same team trying to keep Unchained, Battle, the Dragon robots, etc from exploding on a daily basis haha.
