I haven't paid much attention to the project since it was on the ropes for a while, but it seems to have firmed up quite a bit. After reading the last few pages and HTF's comments, I really want to know how drunk Cameron had to get the Disney folks to agree to spending the kind of money that would be associated with something game changing.
Also, if Disney builds a roller coaster that isn't done by Vekoma, I will be really surprised. Yes, they've worked with Intamin and Mauer for rides, but I've not heard anything good about their relationship with Disney regarding those attractions.
