Forgive me if I don't yet believe the Tron rumor.
I can see how Disney would want a Tron ride in Tomorrowland around 2016; especially since they are working on another movie. But the People Mover track is a big red flag.
Disney was spending upwards of $1 million a month in maintenance with the Rocket Rods, as the speed of the cars was wearing out the tires too quickly. Both the belts on the track and the tires on the cars would need to be replaced so often that the cost of maintaining the ride was just too much for the Pressler-era murderers.
So if the Tron Light Cycles would just be a repainted Rocket Rods, Disney is going to be eating too much in maintenance costs again.
That means they'd need to device a new mechanism to drive the cycles, but if they did that; they'd likely have to redo the track itself.
So I don't know...
