I never thought they would keep the dueling element to begin with, at least not as 2 separate tracks; "möbius loop" like Twisted Colossus sure. Depending on the layout, they could still set something like this up for all we know (like Twisted Colossus). Lets be realistic though. It's more expensive to run 2 coasters than one in terms of maintenance and staffing. Them not moving forward with a 2 station dueling coaster with this is a smart move at least in terms of that. You could certainly guarantee on slow days they would have run one side if they felt the need to cut back on staffing which would not make the ride the same.
