Nintendo will still be my primary reason, mostly because Donkey Kong won't be at USH.
that being said, Monsters was the most intriguing land other wise, mostly because the main attraction of Dragons being a show disappoints me quite a bit.
But if the land is cut, and it was always prophesized as the first to go if need be, I really struggle with finding a reason EU should exist. Nintendo could still fit in USF, MOM could still go there as well, and Dragons would make a good replacement for Lost Continent. (Yes I know the reason is to make more money, I was speaking more creatively)
