Meh, I think it's too simple to brush it off as stroking Iger's ego while disregarding current popular culture and trends in the theme park industry.
Let's be honest, despite good intentions WDI has literally never been skillful at telling the story of the future, Disney Park's management has never been good at maintaining and keeping it fresh, and the public has rarely responded as positively to the classic Tomorrowland theme as it has to popular studio driven IP like Toy Story, Star Wars, or Marvel. Don't blame Iger. He is delivering what the public wants and what WDI and the WDCo does best; popular Hollywood escapism.
