I can't accept the Bourne rumor simply because I have no idea why modern, profit-loving, IP-loving Comcast would go with effin' Bourne, an IP that was basically killed off by a flop last year, for a brand new attraction opening in 2019. It'd be like Disney closing, say, the Indiana Jones Stunt Show at DHS to make a Lone Ranger stunt show. No matter how high-quality the show ends up being, no matter how accessible it is to the general public, there's still the lingering question of "What is even the point of this?" and "Couldn't they have used a better IP?" It just seems completely off to me.
I know it's against the rumor mill, but I actually do feel like Sing would be the best fit here, just because it's right by Despicable Me and Pets. The front half of the park would have Illumination, E.T., and Nintendo for family properties, and the back half would have all of the more adult, thrilling stuff.
