Highly unlikely that the show will be back, considering they just gave all the barges, minus the scenery, back to the barge manufacture, all except for the larger Lotus barge.
The company that did the chassis's for FOF also did the barges for ROL and the mobile stages at HS, along with parades for Universal and DLP. I'm not sure if they are still are building chassis's for Disney.
They stages are now waiting for a new component to be added to them. These new items will lift the stage in the air for it to be "towed" in the event that the batteries are discharged and cannot power the stage out of the park.
