It still puzzles me why people think that Disney is going to come up with or employ some avant garde transportation system. The monorail concept has been around since the 1800s and Disney was far from being the first to employ such a device, so the system wasn't exactly 'futuristic' as many claimed it was. Conventional methods like boats and buses, while boring to some, work fine today to get guests from place to place.
There's really nothing special about getting you from Coronado Springs to Hollywood Studios nor is there a reason to make it special. Fundamentally guests could care less what mode of transportation they take in the morning as they are more concerned about getting to that character breakfast on time or making sure they hit that first FastPass window they reserved three months earlier. In the evening, heads are nodding off or they're glued to their smartphone screens looking at who knows what (probably the next day's schedule) to even pay attention to the vehicle that's getting them back to the place to crash for the night. That care-free, spontaneous spirit that visitors of yesteryear had at the House of the Mouse has been replaced with endless planning and adjusting every day they're on vacation. Now people board the transportation system staring at their watches with their daily schedule on their minds and aren't interested in the 'wow' factor of that system taking them from the parking lot to a place to escape the day to day.
The monorail today is an attraction novelty and will continue to be treated as such until management shuts it down. I doubt Disney sees a reason to spend the money and stick another novelty into the system that is required to be a part of the baseline infrastructure, especially when they've taken away the reason to be impressed by that novelty.
