Looking at IAPPA 2013, trackless ride vehicles/systems seem to be made by several companies. Soon it will be playing catch-up to have a trackless system that crosses over it's own path!
While WDW has trackless systems in the park already, they are not the type which vehicles on different paths can occupy the same space at different times, like in the Asian parks (except UoE.) I think you know the ride type I mean.
Now WDW is not interested in new rides every year. They like a themed land in one park every 5 years and refurbs and "special" weekends to drive attendance. BOOOOOOOOOOOOOOO! I hate this love of the status qua except when it comes to tearing down beloved attractions instead of keeping them and adding to the park with new pavilions.
I want to love you again Disney, but you keep making it harder, with every incompetent choice, to spend the unreasonable money you ask of your "guests".
Shape up in 2014! I hope that's you New Year's resolution!
