^ not necessarly. Dirt was being moved, track was spotted, and Dollywood hadn't announced any details up to that point.
This is just my opinion on what you'll see (if it is the big coaster we all want, and what SDC hinted to at ACE Coaster Christmas):
March 2012 - groundwork, clearing
June 2012 - begin construction
December 2012 - complete major construction
Winter break 2013 - detail construction (testing if weather allows)
Spring 2013 - "The Bull - Wooden Coaster" opens
Of course dependent on size, you could see things begin earlier, or later.......If it's big, I wouldn't doubt you could see things start in a couple of weeks just to be able to make a Spring 2013 date.
