Disney developing 'Lost' ride?

Though firmly grounded in the rumor mill, it seems likely that Disney is workshopping a ride based on the popular ABC (which Disney owns) show Lost. The rumor comes courtesy of Movieline's unnamed mole who stated that some Imagineers were gossiping about the ride's existence at the most recent IAPPA gathering in Vegas. The mole hints at the supposed ride utilizing technology similar to that seen in Epcot's new Sum of all Thrills roller coaster simulation. Again, the existence of this ride is still a giant question mark, but we think the larger question is: Why hasn't Disney made this already?
