I have always been disappointed with DHS, it never felt whole or immersively-themed...a lot of negative space between a handful of attractions. I am excited for the redevelopment of the park, I could still
want more.
AK is a similar but different, most of the park is a return to highly detailed immersive experience, the theming is great (well, weak in the Dinosaur section), I will definitely enjoy more attractions there, esecaiilly since I know the park was truncated and parts not built due to budget cuts (much like DCA).
And, yes, Epcot is getting long in the tooth (some of those WS pavilions are identical, with the same identical merchandise and food, as the day they opened).
Will WDW ever get the same sort of investment that Disney put into making DCA a whole park? Probably not. WDW does well enough, Orlando doesn't have the clout to twist Disney's arm like Anaheim does, and Disney would rather invest to expend their international customer base in China.
But when you view WDW as a "resort"...4 parks...2 water parks...lots of non-park report hotel pluses (I
could spend vacation at a WDW Deluxe and not go to a single park), etc. it's still offers a ton to do.
I am also not so sure Disney is worried about losing much market share to Universal Florida as in many ways they are different experiences and not the exact same market demographic, overlap perhaps with the 14-24 age interested in Harry Potter, but not families with young kids, adults making return visits, or the repeat visitor over 50 age crowd.
from Orlando Sentinel story in May, "Universal's market share last year (2015) was 23.8 percent, a percentage point higher than the previous year. Disney's market share was 70 percent compared with 70.9 percent the year before".
I think your skewing old for HP, I believe the 5-6 yo crowd is where it begins, my son and his friends started reading the books in kindergarten, and plenty more skipped the books and went straight to watching the movies. Plus, what you really need to compare is Universal market-share pre-WWHP and post-Diagon Alley, they've taken more than 5% from Disney in 7 years. But you are right that Disney probably doesn't have to worry about US, if anything it just increases the appeal of Orlando as a vacation destination.Plus, Universal has fewer rides that families can enjoy together, that's Disney's specialty.
If WDW had stayed with 2 parks like DL ..., and then added as much as AK and DHS to those 2 parks,...[.
DL and DCA combine to pretty much the same number of rides as all 4 WDW parks now, all in a space roughly the size of Epcot.
