Not too very long ago the story was floating about that WDI visited a small midwestern amusement park. Imagineers were there to study a trackless system for a popular ride. The system is said to be more cost effective than TDL's Pooh Hunt.
Well, the reason that they were doing so is apparently because Disney is looking to integrate technology in order to develop a cost effective, reliable trackless WALL-E ride. The attraction would be installed in the upper level of Innoventions. The idea of a highly themed restaurant for the lower level is being kicked around - as well as other concepts.
I had previously posted a thread dealing with the possibility of a WALL-E attraction going into the top level of the Innoventions/former CoP building. Didn't here the rumor. It just made logical sense to me. The name "Innoventions" would go, and a WALL-E ride such as I have described just might be comparable to Space Mountain in terms of popularity.
Trackless vehicles and a robot would make for a dynamic combination.
