I understand the complaints about Dinorama being lackluster, etc, but again, why not improve Dinoland, make it awesome, and add Tropical Americas elsewhere? They have the space. They have the money. Add capacity to the park. Dinosaurs are an eternal theme. They deserve a place in the park. To excise them completely is just crazy.
Restaurantosaurus is very themed. Every inch of it is basically covered in theming. Given recent track record of making things more generic, I find it hard to believe it will be replaced with something that is as heavily themed. I am scared we will just get a bland, beige/gray food court.
I rode Dinosaur last week and several children in the preshow were absolutely enamored, talking about this ride featuring Dr Seeker and us going to retrieve a dino. Things don't have to be IP to be successful.
