Just curious, what makes you think Dollywood is being secret? They do have a huge teaser banner that pretty much confirms it as a launched coaster.
Of course, this could be a B&M since they have been working on a launched coaster. In which case it would be very interesting to pay attention to.
Like I said way back in this thread, Dollywood officials were reported touring Europa Park. That makes it likely they will be getting a Mack launched coaster here.
Because this it is as far as any clue goes (if it is a clue, like with the screams being monitors at KI). With Wild Eagle, employees had some idea of what was coming (I do know this for a fact), but this time is very different. The only press release or anything that has been issued actually hinted at more than one attraction (saying "new adventures, "new additions," and everything else in the plural). Near point in the game with Wild Eagle, The Mountain Press had already said it would be a large coaster because of info from a Pigeon Forge planning commission meeting. I think they learned a lesson with WE and are being tight lipped about this one. Trust me when I say I don't know much in this world, but I know Dollywood.
