So you guys are pretty sure about the gondolas then? It just seem like overkill for one resort, and is not real "next-gen". It would have the same problem as a monorail or track based system in that you can't expand on it very easily, but Disney has these trackless ride systems now for things like Toy Story Spin and Google has their driver-less cars. Some type of "Driver-less Bus" or "Driver-less Tram" would get the job done, all it would need is it's own private road way, and wouldn't need to be elevated except for the occasional bridge over the existing roads. this "L shaped" structure to me looks like a place were 2 separate road way would connect, one "express" way just between the Studios and Epcot's Intentional gateway and then a secondary spur off to the Caribbean Beach Resort, and potentially the Port Orleans, Old Key West, ans Saratoga Springs resorts as well
The evidence of the permits is pretty conclusive, not to mention various sources have confirmed it's gondolas. These would actually serve 3 resorts (4 if CBR is split into two resorts as rumored). I think present day Disney is much more interested in "practical" then "next-gen".
