I've enjoyed the multitude of speculation. Amazing!
Specifically - Zero Gravity, thank you for asking the very questions that perhaps you should be answering yourself. From the looks of your postings you're predicting the new attraction for Holiday World to be a B&M ride. And you've repeatedly stated you believe it will be a flying coaster (not the first of it's kind, mind you) with a backwards launch (you're spinning that as a "first of it's kind" thing...meh). It's a nice guess. Birds fly, etc etc... Sorry if I'm missing something in your questioning, but it just seems ironic. I'm looking forward to Thursday with incredible anticipation now!
Just one important technical bit to deepen speculation - the footers running that span some are referencing as the "launch" line are not actually wide enough to accommodate traditional flyer/invert supports that would enable clearance of a 4 across flyer/invert train.
I'll crawl back into the water, now.
