James Gunn also said the ride would fully honor and conform to the original intentions of Epcot's salute to science, the natural world, and human achievement. We have yet to see any evidence that's really the case.
In any case, I hope he's wrong. As much as I don't like the idea of this ride in Epcot, I would at least like it to be an attraction I can experience. If it has inversions, I'll probably never ride it. I have yet to encounter any coaster with inversions that didn’t trigger some amount of lingering vertigo for me, so I just don’t do them anymore.
