I don't see what your point is regarding the opening dates within a year limit, but the what the attraction presents.
Let me put it this way, you are comparing a 100-110 million (just a guess as I think IOA Kong is there) attraction that will have a high capacity in-take as a filler attraction against a billion dollar land with two E-Ticket attractions.
In a way, it's comparing apples to oranges; or in a case as both opened the same year; Transformers in California to a 750 million dollar Cars themed land.
It's just not a right way of comparing things, and that you need to revise what you need to say.
