If they play off the California parks, I can see them naming it "Disney's Florida Adventure." But then I also think that they wouldn't want to be seeing as copying Universal by using the word "adventure" in a park name. Then again, I'm not sure how much of the general public even knows that Universal's second park is called Islands of Adventure. But who knows.
They'll probably shock us all and come up with something completely different. Disney's Your Disney Experience: The Park. Heh.
