I personally believe it is time for the park to add a whole new area, since Wayne's World a decade ago was the last time we got anything on that scale. (Well, Zoom Zone was nice, but it was very small, and aimed more at kids.)
2005: Boomerang Bay 2006: 2 New Flats & County Fair makeover 2007: Impulse & Boomerang Coasters & Thrill Zone Makeover 2008: Carolina RFD Makeover & a new flat 2009: Anamation Station makeover & a few new kiddie rides 2010: Hyper or Floorless coaster.
Thats about as far as i would predict.
