Epcot: Need to do something with the old Wonders of Life, Universe of Energy, and Odyssey restaurant areas. They also need more countries in the World Showcase. Why not turn the Odyssey and that odd little "tribal" area between Germany & China in to India and Brazil ? Those two countries are sorely missing IMHO.
Hollywood Studio: feels like half a park right now what with the construction towards the back and the closure of the Great Movie Ride. But I assume the completion of the construction project will alleviate this.
