1 Disney just bought the company in 2012. Also it would be stupid for them to build something with new movies coming out starting next year. They would wait for the new ones if they were smart.
2. Universal isn't going to overtake Magic Kingdom EVER and Epcot wont be overtaken either. Animal Kingdom and Hollywood Studios maybe, but their numbers get bigger each year and they aren't even doing anything. So you can bet when Avatar opens and the new things come that Animal Kingdom will see a boost and Hollywood Studios will see a boost when they build stuff. Disney would have to sit and do NOTHING for years before Universal could overtake them. Not saying it couldn't happen to the two lowers but if it did Disney would bounce.
3. Two of those tree proposed hotels are looking to be more of extensions to the original hotels. That's why they are small 400 room hotels.
I would argue that Disney has been sitting and doing nothing for years at AK, Epcot, and HS. By the time Avatar is open, it will be close to a decade. If Universal grows faster by about a 7% rate or so, which I would expect (assuming nothing new is announced and built), it would only take 3-4 years for them to catch HS and AK.
Again, I would like nothing better than Disney to recognize that trend and reverse it with Star Wars land and other rides, which is the one property they have that could compete head to head and surpass what Universal has done with HP.
I would also be curious to know the average amount of time guests spend in the park. I wouldn't be surprised if the total guest hours in the parks is already equal between the two. So many people do HS and AK as half day parks. Also, average paid admission would be interesting as well. I wonder what percentage of HS and AK are 4-7 day ticket, vs 1-2 day. I bet total gate revenue is pretty close already as well. Now Disney is way ahead in average guest spending, even with HP included. Thats a gap that would probably take decades to overtake!
