Here's the future line-up at the Tokyo Disney Resort (TDR):
Tokyo
Disneyland DisneySeas
2004 Waterfront Park
2005 Buzz Lightyear
2006 New Roller Coaster
2007 Tower of Terror
In addition, fundamentally addressing the problem of concentration of guests at Tokyo DisneySea will require large-scale capital investment to introduce new attractions, including
construction time.
By the numbers: Tokyo DL DisneySeas
42 attractions 23 attractions (**)
In contrast:
Disneyland CaliMisadventure
61 attractions (*) 33 attractions (*)
(*) These numbers are inflated by the website to include:

Meet and Greet with Goofy and pals
Horse Drawn Streetcars, presented by National (are you kidding?)

Meet and Greet Winnie The Pooh
CaliMisAdventure:

Meet & Greet Flik & Atta
Meet & Greet Chip and Dale
Games of the Boardwalk (I'd pay $47 to play carnie games, sure.....)
Golden Winery
Tortilla Factory
Puddle Park (in the old days, they didn't even advertise water play areas like in Epcot or DTD, they were just *suprises*)
Boudin Bakery (are you kidding me?)
(**) Tokyo DisneySeas counts in its 23 the American Waterfront vehicles, transit locations, the Gondolas, and the Fortress, but still has either 19 or 20 legitimate attractions.
As for WDW, I am a firm believer that each park should get a new E-ticket ride every 4-5 years, to remind folks to come back every 3-5 years for another visit. Smaller attractions and shows should be added nearly every years, tied in to the latest animated features. There should be no down areas like the lagoon...I have found no long term closures at the Tokyo Disneyland park, even though it has been open for 20 years this year.
