No new attractions will be coming to WDW for DL's 50th.
All parks will celebrate Fifty Years of Disney Parks with small tributes and signage, probably focused at one park (Like 100YoM at MGM). The closest thing too a new ride at WDW at this time may be Everest, if it gets done by0 late 2005.
DL is getting a rebuilt Space Mountain, a new parade, a new fireworks show, a repainted Small World, possibly some sort of walk-through tribute, and a soon-to -be-announced Buzz Lightyear. The major rehabs and added scenes for the classics is out. And were it not for Jay Rasulo, so would be Space and Buzz.
Oh,and there will be pins....lots and lots of pins.:snore:
