The problem with adding the imaginary now is that it has been open for several years and by adding it now, it messes with the feel of the park. For me, at least. I would much rather see Australia or some other part of the world that hasn't been showcased by either AK or EPCOT yet. So many real places on Earth for kids and adults to learn about/experience. I just don't see the point of a fake planet with fake people in a park as beautiful as AK. A ride in DHS would be fine, though. Even with two upcoming sequels, which are also reported to now be delayed, I just don't think it will hold the interest/appeal that Disney would want to invest in for the long term.
