The idea that people are going to leave Disney in droves for Universal is delusional. I'm sorry, but I don't understand this mentality.
Harry Potter single handedly saved the parks sector of Universal. They've been able to strike deals for other IPs since, which is great for their portfolio.
Further, I have to ask: why are people so invested in what Disney does to combat Epic Universe? It surely isn't because these individuals care about Disney "losing its hold on the industry?"
Steering back to D23 Expo: Disney made announcements that they are committed to implementing. And now that time has passed since the presentation, I think I prefer this parks panel approach over a breadth of announcements being cancelled and never being mentioned again.
Personally, I think sharing news at this Expo is important (if you're going to hold it and charge admission, make it worth it)—but it's also become clear that they want year-round buzz for the parks. They consistently publish on the Parks Blog about food, merchandise, and events throughout the year. But what if, and I know it's a what if, Josh is shifting the mentality that year-round announcements of large Parks information is the way to go? Why NOT announce a new land, attraction, or experience on a pre-determined date mid-year and keep the Parks buzz going instead of during one big event?
