Busch Gardens released the website for Christmas Town 2010 today:http://www.christmastown.com/homepage.aspx
As far as the ride selection goes, it looks the same as last year, with Griffion being the only coaster running.
I was a little disappointed that the entire park wasn't going to be used. Italy, Fiesta Italy and the area around Pompeii are omitted from the map again this year. Sesame Street Forrest of Fun and Land of the Dragons (the two children play areas) are also both not on the map.
If you go to the interactive park map section you will notice that Katapult is missing. I know first hand that Katapult was running during last year's Christmas Town because I rode it and froze on it. Looking at the map, it looks as if the park ends around the swings.
