Personally i'd rather a 2016 ride system than a mid-90's one for IJ. If I want to ride IJA, I can go to Disneyland. I'd rather have a unique IJ ride in WDW. The ride system is the only legit "people-eater" that has been developed in the Iger-era, too. It does close to 3K/hour capacity. Put this in either DAK or DHS and you've majorly helped out with park capacity issues.
Should also be noted that according to
@Marni1971, the real fight here is really for which park gets the Shanghai Pirates ride system... it may not even end up using the Indy IP.
