I have a very good feeling that "What Will You Celebrate" will be extended into 2010 as well, meaning Celebrate A Dream Come True Parade will last until the 40th Ann. in 2011. I did have hopes of POD coming to WDW in 2010 but I doubt that will happen unless it will be considered WDWs 40th Ann. Parade, only starting early. Anything is possible I suppose.
Just a speculation and not saying that would be a bad thing, although I doubt very much Disney would want to give away free admission on everyones Birthday for another whole year.
I found the music to be too repetitive, also, the show stops I felt were boring, and the choreography was bad. Also during the show stops, I found the colored flags to be out of place and same with the men's outfits. I did like to women's outfits and the wigs. If I could change one thing about the parade, it would be to get rid of the flags.
