Yeah - what about Crush's Coaster? People have reported this ride as being amazing, but yet sounds family friendly enough that it could take a lot of stress off Toy Story..
I think the problem with Crush's Coaster its the low capacity it has. It has a constant 40 minute minimum wait right (often much more) from park opening. And while it is a fun ride - I would not call it amazing. It is an off the shelf Maurer & Söhne coaster which is in the dark and nicely themed and has a "dark ride" portion at the start of the ride. It also has a 42 inch minimum height.
But as usual with Paris, there is never any official confirmation until near opening anyway. So who knows? haha
Well, Philippe Gas mentioned in a newspaper interview that there will be a new attraction opening in 2014 and as I understood it that is taken as a reference to the Ratatouille ride. After all there are cranes on sight according to the pictures I have seen, so I guess they are already building it. I guess the question is just how much the budget will be cut during the building process, so who knows what we really will end up with...
