"Quite a few things"? Did WDW open some secret attractions I don't know about?
Absolutely nothing as mainstream noteworthy has been built at WDW to near any level as Universal in quite some time. The closest they came, Everest - well, Disco Yeti is all that needs to be said there.
Playing catch up - funny choice of words, since many folk insisted Universal was never a threat and never would be. You will find most of those people don't say that so much any more.
When this is said and done, Universal will still only have half the hotel rooms of WDW, very true - but a few years ago, that would have been unheard of, crazy talk from even the most ardent supporters of Universal (which, most of us aren't - but we recognize the truth of the situation which is that Universal is killing Disney in the business of making new and innovative, exciting attractions).
I mean, you even listed the "bigger downtown complex" - LOL, much of which was shuttered for the larger part of the last decade, and consistently is in flux as they try to figure out just what to do with it? Don't see many shuttered doors at City Walk...
Well you just hit the nail on the head. Disney is spending a billion on a bunch of fancy bracelets to get the rocks of super-planners excited, that won't even be available to the average guest, solely for those who don't realize the utter absurdity of planning a fast pass for an attraction six months before the vacation. Universal is building huge amazing new attractions that make headlines across the world, and Disney is doing something that they can't even make a television commercial about, and would need an hour-long infomercial to even explain it, if they tried.
It was good for the Mouse when Universal was a one-day deal that kept people in the area longer. It's not good for the Mouse that Universal is attracting brand new customers to Florida who are coming to them as the main attraction and not the sideshow, while Disney is content to sit and tinker with their existing die-hards trying to trick them into spending a few more cents by giving them a payment device that supposedly disassociates them from money. Disney was adding mostly crap served over watered down crap, but - the point is not the past. It's the future. It's right now. And right now, Disney is getting trounced in the most important aspect - attractions - and it's been that way for awhile (Spiderman was regarded as the highest rated theme park ride in the world since it opened, and didn't get outdone until Universal bested itself with Harry Potter).
You are right, Disney and Universal are playing in different leagues - Disney has sat squarely on their laurels, and Universal is kicking their butts now, and for the foreseeable future.
I want to be wrong. We all do. But no amount of wishful thinking or justification for sitting around five years waiting for a little hill to be built in the same time Universal has added a roster of attractions that makes world headlines and continues to do so will change the fact that while it's not pretty, it's reality that Disney is almost conceding that they are no longer in the business of new, innovative attractions and simply wish to keep milking what they already have and trying to squeeze a few drops more.
