Who was it that claimed the company is slow to develop projects?
Regardless of the "when" the Disney theme parks will maintain their (VERY healthy) marketshare. And there is absolutely zero competition that will draw significant (impact) business away from their models.
IMO if it's an attraction that beats the Harry Potters FJ, then its a win.
I will never understand how Disney decided to develop Hollywood Studios in the manner they did on the land they chose. I can't fathom much worse use of the acreage, with the parking lot sitting right in the middle of it. Had it been thought out better, the park could have been at least twice as big, but from the start, it was about as poorly planned as could be imagined.
So I look forward to Star Wars and CarsLand East, but until or unless the park is actually expanded, I can't say I'm ever going to truly be happy.
Expand the park out into the parking lot (which would require a complete rearranging of the bus area [and hey - an opportunity to finally get a monorail to the park!] and moving of the entrance). If parking garages can exist at Disneyland and Disney Springs, I don't see why HS can't have one or more. It's too small of a park, and no matter how many new attractions or lands they develop within its borders, it's still going to suffer.
