I just thought of something. What if this is one of those next-gen Vekoma launched flying coasters? The layout would be perfect for a flying coaster (especially with all the weird sways in the track), Dollywood has worked with Vekoma before, they could easily theme it to butterflies or a bird and have it fit perfectly into the surrounding Wildwood Grove, it wouldn't be that intense so it could qualify as a family coaster, and it's very different than both of the other launch coasters in the park. It would also be the first of it's kind in the States. The only real hurdle I can think of is the new manufacturer thing, but the layout was still in flux as of four months ago so the manufacturer could have been as well.
