( From a Disney Cast Member )
The 40th Anniversary for Walt Disney World will only involve that one resort - This means Disneyland will not be part of it Yes, if the 40th is still a go, it will be a WDW-exclusive celebration.
Space Mountain will reopen early 2010 (We know that already ) As of right now, yes.
The Castle will assume be decoroated since there was one for DLP TDL Possibly, but not a definite. This depends solely on marketing's integration of the resort's assets when the scope of the 40th is fully determined.
New Mark VII Monorails set to be September 2010 Not that I've heard... Actually, WDW's existing fleet has been performing quite well for their age. No replacements are expected for at least five more years (at the earliest extreme).
All moderate resorts to be renovated No guarantees, but again, possible.
Toy Story 3 Characters to be placed in parks Like Martin said, this would be a promotional move for Toy Story 3, but from what I've been told, they will only appear at Hollywood Studios and Magic Kingdom.
Polyneisan is to install hot tubs Not quite sure about that one.
Test Track Will get a new sponser witch means New Pre Show Car show at end. Ford has a connection with ABC = Disney New sponsor, preshow and post show is a yes... But the exact financier has yet to be determined. As of right now, Ford isn't looking too likely either. I've been tipped in the direction of the Japanese for this one.
well thats all the info so far
