I believe A Monorail announcement will be coming. With the opening of the skyliner, construction to the front of Epcot, and the building of the bridge from GF to MK they have a few projects that seem to hint at the future.
Consider first why they are building a walkway from GF to MK? It's a nice add, but not one that really benefits Disney much. Except if say the Monorail line will be down for extended maintenance. It gives people staying at Poly and GF the option to walk to MK instead of waiting for a bus. The skyliner opening gives them a field group to study and get a reaction to regarding comfort, etc. On top of that the entire front of Epcot is being worked on as we speak. Adding the removal of that monorail line falls right into everything else that is being done.
Many people think the skyliner will be expanded, and I could see this being the next addition. Epcot front to TTC.
I have no insider knowledge about this, buy from everything I have read and do know of regarding the Monorails. This makes sense as there next move. Redo the system around MK, and eliminate the Epcot line. That line is horrible at park closing to get back to MK resorts. You could wait for 2-3 trains just to board. The constant loading of the skyliner would handle the guest flow much better. Even if it's a longer ride, you wouldn't have to wait to board and you'd be guaranteed a seat for the trip.
Here is hoping they do something.
