I cannot say for certain, but from what I have read on other forums/posts is that every year they have to "Renew" the list and since TRex and Rainforest are not owned by Disney, they have to have an "Agreement". As such it's possible that they have not yet come to an agreement yet. It's also possible that they have come to an agreement but haven't updated the site yet. If you are not sure, I would call directly and ask them.
