I'm sorry, but I need to interject here - when did we decide that success in the parks is measured by technological achievement? Yes, Animal Kingdom is not breaking new ground with it's technology (We'll see if that continues with Avatar), but it still has numerous experiences that you will not find in any other Disney park, let alone any standard theme park. This is also on top of some of the most extensive theming across the complex, one of the most popular and well received stage shows, and more.
So no, it may not be delivering some new technological marvel - but if that's what you (And I don't mean to single you out, mostly using this as a statement) deem as necessary for a success, you are most likely to be disappointed in whatever Disney/Universal does.
