Honestly, there aren't enough Dr. Seuss movies to justify remaking the entire land at IOA due to how expensive it is and would have ruined the guests' experience. Not that it matters anyway, but I don't really see Dr. Seuss Land being reconstructed to match that of the movies. Of course, it would be easier for Universal to build Dr. Seuss Land to match that of the movies they distributed and don't have to share money with anyone, but live actions are harder to sell than animated ones. They might keep the book version the way it is.
