Anybody that would like to see this happen should be afraid. Not only from their complete lack of understanding that Epcot plays a unique role in balancing out the parks and experience, but more from what is happening in Norway. 2 years for a sure to be lackluster Frozen ride, which is based off a movie that was far more popular and grossed waaaaaaaay more than Ratotouille.
If you hear any news of the rat coming to France Pavilion, keep you expectations low, ... Im talking Florida water table low. And be prepared to wait a few years from the initial announcement. Then expect a few of the effects to be offline when it opens, lol.
If anything comes I'd expect it to be a clone of the Studios ride in Paris which is a decent ride. Not great but not bad either.
