You can't compare Comcast to a company that plans to take over 3 years to build a clone of a ride with insane budgets that already exists in Shanghai. I'm always befuddled by Disney construction timelines and overall costs. Complete, fairly well themed, park are built from the ground up quicker than a Disney Coaster. It took Efteling and Phantasialand a little over a year to build their last two, highly themed major coasters. Look at what Mack is building, a very detailed, themed resort with water park in two years. And...Tron will take 3 years?
