Pandora also cost $$$$$$$$$$$$$$. This is a much smaller project. So I highly doubt it will be that detailed/lush.
Also on the ride/no ride debate. I do like more rides, but I think part of the appeal of the countries is that there aren't rides everywhere. It allows you to enjoy the theming/shows, eat/drink, and shop, without the pressure of getting a fast pass, or waiting in a long line. A "Carnival" type daily parade or show would be pretty popular I would imagine.
