I think you guys may be taking things too literally here. Clearly, the shot tower and the L'il Swings will be here, but outside of that we can only speculate. The Bucket Brigade in the concept art suggest a probably high chance of definitely having a "ball pit" type attraction in the area, too. Outside of that, I think the big/little discussion means that this is the little addition, and the big addition will come later in the form of a coaster.
And if you are just joining us, other than there being a firefighter theme, don't you think they will leave the Bald Knobbers to FitH? I would love it if there would be some wanted posters or something around the FL area, but I wouldn't hold out any hopes for that.
