As to Dinoland or more apt, Dinorama and the space available around it, nothing has been firmly approved ... BUT ... providing Pandora does the trick and actually turns DAK into the 'full day park' that it really has been all the time, except for people who want to ride Space Mountain 13 times in a day, it is very likely. As to what will happen, plans can (and do) change. But what is likely is Disney resurrecting a name from the past, using a concept from another park in the past that was never built, and updating it with new tech and some old friends.
