Some have asked if Avatar will be relevant 10 years from now. I would suggest that Avatar is not relevant in popular culture now. I don't recall seeing anyone wear a blue people t-shirt anywhere. However, if it is a beautiful, fully encompassing environment with great attractions, I think it will be a good addition to DAK.
With that said, I believe TWDC is trying far too hard with DAK. Pick a continent that is not represented (either of the Americas or Australia) and build an Africa/Asia style area there. Take a bulldozer to the Chester and Hester area and build an incredible Dino land BEFORE Uni announces Jurassic Park. Make Uni go a different direction from their rumored plans for a change. In the new Dino land, have a night time spectacular and DAK is a full day park.
