Yeah, thought about it a few minutes more and realized what could have happened: Original plan called for a "larger," TRON-style coaster with a brief outdoor section and the majority of the ride path inside in a big show building (read: relatively inexpensive show set). Dark ride was a sizable but not extravagant affair.
New plan potentially calls for scaled up E-ticket dark ride and a coaster more along the lines of, say, Slinky Dog or Seven Dwarfs Mine Train.
