Well Six Flags has definitely kept things incredibly hush so far. All people can really do is try to piece their own pieces of information together, which seem accurate, but at this point no actually "hints" or "leaks" have been released really by Six Flags or anyone, and there is no actually pieces of legit evidence that proves some of the claims made by certain people will actually happen. (Those surveys? Yeah, they were fake. Of course not every park wants an S&S 4D Free Fly.) Piecing together information means nothing unless the attraction is obvious. (ex. Valravn, Lightning Rod) I know Valravn was given without any sort of purposeful leaks from Cedar Fair, but there was a legit leak from a newspaper source, which really can't be argued. Have any leaks, or any other hints like that come out for Great Adventure? Not really. Otherwise all of us would have known by now.
