The thing is, Disney doesn't have to fight the war. And their current rides show that. SWGE is not well received. The TRON coaster is very basic, and destroys its own theme, and Ratatouille is a nice kids dark ride.
GotG and RotR are the two wild cards still that may be awesome, maybe not.
But for 19 years, Disney didn't build crap, and their attendance kept skyrocketing.
Another phenomenal Universal park will likely hurt Seaworld and LEGOland more than Disney. Evan Hogsmeade didn't really hurt Disney.
Universal HAS to announce a Magical Express equivalent, IMHO. Hell, it needs to start like tomorrow. Maybe even set up a deal with Seaworld for busses between resorts. Uni and SEAS together could maybe chip away on Disney. There are too many people who think not having a car is a huge positive. They can't math enough to realize the food costs, and now especially with Disney charging you parking anyway, a rental car costs you $200 for a week stay just in parking at a Disney resort. That, along with all the DizNoids saying how awful Universal is keeps many from ever going. Disney knows once they go once, they are likely going to change their Orlando vacations forever.
