The way I read this and other information is that this will be a change for awhile. I guess they designed this ride to be able to do this, switch out a new game for another. I can't imagine them taking it away before they switch any of the other original games first. So, no need to rush over in May, or June when I will be going.

If I could wait to see this I would wait until September, actually when hopefully the Summer crowds will be gone. At least that is my opinion with what I had read.
Good Luck with the surgery.
