I would really be surprised if they axed space fantasy the ride, for the nintendo area I could see them taking out the area that they currently use for the 'cool japan' since there's a 4-d theater there and basically an office annex that they use for special events. And off the topic of nintendo, I have nothing but love for the park because it really is a "weird, unique universal time machine." Because you have some of the best rides in Universal history blended in with some of the current huge attractions like harry potter. One thing they bearly talk about this park that I love, is the amount of people that cosplay which this place is perfect for it. <- link to that evidence.
TL;DR
I love the park, its cool. I'm happy I bought an annual pass.
