Actually, disney was ______________ throughout much of the 80s until Eisner came along, and then the company did well for the rest of the 80s and most of the 90s...I mean, you look back to years like 1994 at just attractions, not including hotels, opening at disney, you see that the slowdown was recent:
1994: Legend of the Lion King, Innoventions, Honey, I Shrunk the Audience, Food Rocks!, Tower of Terror
1995: The Circle of Life, Alien Encounter, Blizzard Beach
1996: Toontown Fair, Ellen's Energy Adventure, Hunchback, Fantasia Gardens
1997: Downtown Disney West Side, Wide World of Sports
1998: Animal Kingdom, Buzz, Enchanted Tiki Room--Under New Managment, Fantasmic!, DisneyQuest
1999: Sounds Dangerous!, Kali River Rapids, Maharajah Jungle Trek, Test Track, Rock 'n' Roller Coaster, Many Adventures of Winnie the Pooh, Cirque du Soleil
2000 onward were pretty slow...Disney slowed down when the economy did...but I don't think anyone could expect them to continue to open as many attractions yearly as they did...I listed 26 things in six years, including West Side, DisneyQuest, Animal Kingdom, and Blizzard Beach, which all include many of their own attractions. Being conservative, they opened 50 attractions within a six year time-span...if you look between 1971 and 1988 or so, you will see that the rate of additions was much less, usually a couple attractions every other year or so...
But, you talk about "catching up". To what exactly. I have not seen very much from Universal since Islands of Adventure opened, and Universal has ONE high-tech attraction that I know of, Spiderman. Disney World is opening a little project this year called Mission: SPACE that is one of the most high-tech in the world...(not going to say THE MOST until I ride it...).
